This morning the OpenID Foundation announced that Google, IBM, Microsoft, VeriSign, and Yahoo! have joined the board. This is good news, since OpenID is good.
However, there are limits to the goodness of the news. As Michael Arrington points out:
OpenID looks like it’s going to be a winner, so big companies making their user accounts OpenID compatible is a good hedge. Everyone, of course, wants to be an ID issuer, since they get to “own” the user. Less attractive is allowing users from other sites to log into your services, so don’t expect that functionality to come for some time.
