Personas and Blogging
Mark Pilgrim has an interesting weblog: Dive into Accessibility in which he discusses and provides new approaches by which "bloggers" can design their Weblogs for people with disabilities.
Although his entries are quite long he really delves into the subject and even uses character sketches of five real people with various disabilities including technological, which makes it difficult for them to take advantage of the Internet.
It's a pretty interesting read, particularly when you get to the sections where he provides his 25 tips on making accessible sites. The tips are all compiled from his interactions with people with disabilities who listed the features they would prefer to use when exploring the Internet; for instance, web-safe colors, identifying the links for images and so forth.
Although we all know about the Internet and accessibility issues, I found it interesting that Mark targets the blogging community. Thoughtful though.
