I'd much rather have "login with openid" rather than seeing "login with twitter ; login with facebook ; login with posterous" or whichever subset of sites any random service thinks is most valuable to support. The great thing about login/identity/authentication standards is that there are so many to choose from. Didn't we learn the first time around with web browser capabilities to avoid this kind of fragmentation again?
