I won't be commenting on techcrunch because of this change, and if I can't comment I'll be less likely to visit regularly. I liked disqus .. and I'm annoyed that Facebook is invading this space.
I'm curious why you won't be commenting? What does the new interface lack that Disqus had (or vice versa)? Or is it merely your annoyance at Facebook for trying to build something better that drives your decision? (Keep in mind, no one is forcing the Facebook comment widget down publishers' throats. Perhaps it bothers you because it feels like it's more optimized for publishers than users?)
I don't want to use my Facebook account for anything other than facebook.com. I don't particularly trust Facebook as an organisation and I certainly don't wish to live in a world that's dominated by only one or two huge mega-corps.
