Personally I feel a lot better about Twitter + OAuth than FB, but that's just me.

As for why not use OpenID? Personally, I don't want to tie my Gmail account to a lot of things -- then people have my email! I don't necessarily want to tie my Facebook to them, either, but in the same breath some forms of OpenID can end up sharing more, depending...

This is why I get cranky when people implement Disqus, too -- old comments I made that were supposed to be anonymous but which had my email for the author, etc, are now pulled in and linked to a general identity months or years later. :(

Why would you feel better about Twitter + OAuth than FaceBook + OAuth (which is what the sign on component of FB Connect is)? From a technology perspective, it's the same protocol. Neither company has a good security track record.

(not criticizing BTW, just curious)

the twitter account could be a throwaway account and generally lesser risk of anybody getting too many personal details.. facebook, not so much ..
