Apparently, that Classic ASP script does work. It seems that the Twitter account I was attempting to follow was one of those that holds followers pending until approved. Theoretically, you could have a link to the script and with ajax make it so people with Twitter accounts who are signed in could follow you with one click. Theoretically ? you could have a form that they put their login credentials into also, but that would not be secure, so perhaps that wouldn't be a good idea.
