I never liked Facebook Connect. A big part of that is because I’ve never had a Facebook account. I don’t plan on getting one anytime soon, especially not to try out an app. The spammy feelings, for me, come after that.
It’s interesting to me that Facebook Connect gets a lot of backlash, but people keep using it. I realize it’s the majority using it, not those of us that truly understand the implications of logging in via Facebook Connect, but there are still lots of us out there.
It makes me wish OpenID survived, single sign on in theory is a good idea, just so long as it’s just that, not the equivalent of leaving your unlocked mobile phone in a bar at a marketing convention.
