One of the best papers I saw in the whole web 2.0 conference held at Royal Holloway a few months back was given by Dr Helen Kennedy. Helen spoke about how people with learning difficulties were being excluded from the web and designers gave little thought as to how to structure websites in such a way as to make them useful and accessible. It was certainly a very thought provoking session.
For that reason I was thrilled that Helen's work was featured on Channel 4 news yesterday. I do have to declare a slight interest (the report was put together by a Channel 4 researcher who is a friend of mine) but they did a really great job.
