Web 2.0 Evolution

Web 2.0 & Accessibility

Web without web?

Posted by iljitsch on October 17, 2007

Is the answer to web 2.0 really web 3.0? I’m starting to think that less web might be a better next step. For instance, when I read RSS feeds I see the posts formatted in a standard way by the RSS reader, rather than having to deal with a completely different layout for every site. And a program like iTunes gets different types of content from web servers, but it presents its own interface optimized for use as a media player rather than acting like a web browser. Then again, I’m of course extremely old fashioned when it comes to this stuff…

An alternate search engine

Posted by palolo on October 17, 2007

Since we focus on the evolution of the Web perhaps some of you are wondering if search engines are evolving. Of course, most of the people will think about improving algorithms for finding the desired search, avoiding fake page rankings or offering new search criteria. Well, an australian company named Heap Media thought of taking advantage of the popular Google and create a search interface that will save energy. The ideea behind the concept is not new, as we all know that computer monitors require more power when displaying light colors than dark ones. Consequently, they have created Blackle, a search engine powered by Google Custom Search who according to ones could save around would Save 750 Megawatt-hours a Year if it were used instead of the classical version. By the time of my post it has already saved 256,105.223 Watt hours so why not trying it yourself!

Web 3.0

Posted by Rafa on October 17, 2007

I just found this page which provides a definition of Web3.0, which is considered as something around skillful individuals providing great content to the web, and using Web2.0 platform.

While web 2.0 stills needs to be developped and be spreaded through as many people as possible, next generation web definition starts to appear. I would have expected the definition above to be included as part of web 2.0, and consider web 3.0 as something really innovative, I do not know, maybe about providing intelligence to the web (this is called semantic web, isn’t it?).

And another topic to consider is timeframe. I think we are very far from web 3.0, or not ??

Browse the web (2.0) text-only with Lynx

Posted by iljitsch on October 17, 2007

A really long time ago before there were graphical browsers, you could browse the nascent world wide web with text-only browser Lynx. I downloaded and installed Lynx on my Mac. This turned out to be a version from 1999, although there have been some updates since then. The image below shows you what this blog looks like with a text-only browser that doesn’t understand CSS, JavaScript and all the other modern web technologies.

But a well-designed site is still usable this way.

Bringing Accesibility to Web 2.0 (FireVox)

Posted by Rosa Delgado on October 16, 2007

Take a look to this link, i think it is very interesting.


Related to a comment in our old web site, i think Accesibility should be “A must”, and every internet users should  work on it.

Social networking and Web 2.0

Posted by Rafa on October 15, 2007

Social networking is a concept that includes many innovative new services that have appeared on the internet in recent years. What these services have in common is that they attract many groups (or communities), where the participants (such as friends or family) share common interests.

For example:

Flickr is a photo-sharing website where people can upload their photos and share them with friends.

Del.icio.us is similar to Flickr, but where the objects are web locations instead of photos.

One of the most exciting directions of social networking is integration with mobile devices. For example, dodgeball is a friend network and dating service that works with mobile text messaging. When members want to meet someone, they can write a text to Dodgeball with their location and find out where their friends are. Another example is nanoblogging sites (see my previous post) which are integrated with mobile devices.

So, the social networking phenomenon is great, but its fusion with mobile computing can be extremely powerful for the web 2.0 world.

Google Accessible Search

Posted by be_Productive on October 15, 2007

Accessibility is more important in web services every day. Like other post told, there are many people who have difficulties accessing websites, and we can, step by step, try to reduce the problems to access to internet services.

Nowadays, Google is the most popular web search in Internet, because of this, I was looking for how Google work in accessibility applications and I found a new product…

Accessible Web Search for the Visually Impaired is a new product that Google released to enhance the search. First result pages are considered more accessible than result pages in normal Google.

Google Co-op is the technology which created the new tool. It’s a users’ community where they contribute, with their experience and knowledges, to enhance web search for everyone. Co-op modify result pages about different topics or interests.

In my opinion, work in accessibility pages is so important, we don’t know who is the new Einstein or Bill Gates?!?!

Nanoblogging (or microblogging) are web pages where users create networks and communicate between them using short messages. Most famous one is Twitter, although the reason for my post today is that Jaiku (probably the second most famous nanoblogging site) has recently been acquired by Google.
As you know, Blogger was acquired by Google some years ago, and now they have acquired Jaiku.
To be honest, although I do have a Twitter account, I do not use it (my life is too boring to be shared every minute 🙂 ). But with the Google acquisition probably nanoblogging sites will become as famous as blogging, and with the mobile integration they can even be a similar revolution as the SMS message were.

Active content = less accessibility, more misery

Posted by iljitsch on October 14, 2007

A while ago, I wrote this rant. Since web 2.0 is also often used in conjunction with AJAX (asynchronous javascript and XML) that powers all these neat tricks that can make web applications behave (almost) like real, local applications, I thought this might apply somewhat to our discussion here. So:

Embedded programs that are supposed to enhance our content are in fact making it less secure, less reliable, more expensive to create, promote monocultures and limit consumers’ options. This problem is most apparent on the web, but it’s permeating elsewhere as well.

Phishers trick people into revealing sensitive data by making the user believe he or she is dealing with a legit outfit. For instance, when you hover your mouse pointer over a link, normally, you’ll see the URL the link points to. But with some scripting, it’s possible to display something different. That’s bad, but it gets worse. It’s easy to scan an HTML page to determine if there are any undesired URLs in it. But if there is a script attached to that page, this is no longer possible, because the script can be programmed to construct the unwanted content when it’s run.

Less reliable: if you have a browser display an HTML page with some illegal HTML in it, in almost all cases, the result is usable to some degree: the browser ignores the HTML it doesn’t understand and goes on to render the rest. But with a JavaScript program, if there is one statement or function that the browser doesn’t understand or implements in a way that wasn’t expected by the programmer, and in most cases, the program can’t be executed at all or it fails to function to any useful degree.

Because programs are so fragile, it’s necessary to test them in all environments where they’ll have to function. This is why it’s so hard to surf the web with a browser other than the two or three most popular ones: content creators don’t test their scripts on these browsers, the content doesn’t work, and people switch to Internet Explorer or Firefox.

When DVDs first appeared, only the FBI warnings were unskipable. But having the ability to restrict the use of certain DVD player functions, DVD creators soon started making previews and ads unskipable too, sometimes even forcing users to go through menus to select different soundtracks or subtitles.

Please stop this proliferation of active content, for the most part, it’s not making our lives better.

Predictions about the web accesibility & Web 2.0

Posted by Rosa Delgado on October 13, 2007

I have been reading about web 2. and web accesibility, and i have done a summarize about some predictions and conclusions:

There are three major factors that will shape web accessibility in the very very short future: AJAX, user generated content and WCAG 2.0. The increased prominence of these factors could lead to some of the following:

Accessibility will become less and less guideline-driven
With the advent of new technology (such as AJAX), and the technology-neutral and vague nature of the new W3C guidelines (WCAG 2.0), accessibility is becoming less and less guideline driven. This means that employing accessibility experts is going to become more and more important for organisations as interpreting these guidelines correctly will become more and more difficult.
Alternative accessible versions will become the norm
Historically speaking, separate accessible versions were frowned on for both ethical and business reasons (see Separate text-only version? No thanks!13 for more on this). However, for the first time usability and accessibility are coming head-to-head with each other and rich interactive interfaces often can’t be made fully accessible. In this instance, a separate version will have to be provided (but only after all other routes have been exhausted).
User generated content is likely to offer poor accessibility
Content created by users is becoming more and more commonplace on the web. This kind of content is being created at such a rapid rate that it’s going to be impossible to police it for accessibility.
JavaScript, PDF & Flash will no longer be thought of as ‘evil’
In WCAG 1.0, web managers and developers were basically told that their websites shouldn’t rely on any of these three technologies. WCAG 2.0 on the other hand doesn’t stipulate this, and rightly so as most assistive technologies can now support these technologies.
