Last week Typepad changed the way comments were authenticated, putting up one of those computer generated two words of mixed letters thing. The first time I saw it I tried putting in the letters but many were impossible to make out. Why Typepad thinks its a good idea to follow the bad ideas of other blog companies I do not know.
But, it also looks like there is a sign in drop down box in which a commenter can sign in to their facebook id if they have one or a few other options. This has become the way of doing things in the comment business on most newspaper etc websites. I guess we're stuck with it for now.
But, signing in with Facebook or Twitter or some other ID does not send anything to your facebook page or anyone else's, its merely the blog site's way of knowing commenters are real person not spammers from overseas.
