David Ball has written a follow-up to his excellent article “Things I learned by pretending to be blind for a week“, where he discusses why title text is not as useful as we’ve been led to believe, and what to do about it. Please, if you haven’t already, go and read his article: “I thought title text improved accessibility. I was wrong.“
Here’s a gem that just has to be widely disseminated. Jukka Korpela has written a nice guide to using special characters in HTML. I reckon it covers the problem pretty comprehensively, so rather than try to write one myself, I reckon everyone should check out his guide.
