I read the article Web 2.0 and Accessibility: How You
Can (and Should) Have Both and learned much about web 2.0 that I did not know before. I never knew the importance of caption to videos on youtube or uploaded to facebook but when thinking about the deaf members of society this is very important. I also understand from reading my article as well as Lindsey's ajax is a big problem for screen readers. This issue needs to be resolved because without screen readers most blind people can not use the Internet. I am encourage by both articles because they not only state the issues but give ideas on how the issues can be resolved. My hopes are that these solutions will become requirements for creating web 2.0 tools.

This is a great article defining web 2.0 and discussing one of the accessibility issues with web 2.0.
