I’ve been reminded that the comment verification process that Typepad uses to screen out spambots is inaccessible to blind people (see the discussion on Wikipedia). As a former employee of Benetech, which runs the Bookshare.org service for visually impaired and print disabled individuals, this does not make me happy. Unfortunately, however, there are no good alternatives to the verification process, which is necessary due to the proliferation of spambots. So I want to post a standing offer to any blind readers – you send me comments and I’ll post them for you.
