While I don't use OpenID myself, there are a number of users on my social network asking for its integration. It seems that many users are now beginning to *expect* Web 2.0 startups to provide support for it (just as they did for Firefox). I anticipate that, in the future, when big name startups like Digg and LiveJournal begin supporting OpenID, there will be a huge following by other sites as well. Put simply, crowds follow crowds.
I have read up on OpenID's specifications and what it aims to deliver. If it is labeled a bandwagon, I think it may be a good one to jump onto. There a few provisions one must be wary of regarding security, but for the most part I believe it is a move in a positive direction for managing web identities.
