Seems to me like the big winner, at least right now, is Twitter. Granted, I've only picked up an invitation this morning and haven't fully played around with Google+, but the amount of traffic and hookups on Twitter is amazing.
So, after these guys help out so many other people by getting them closer to an invitation, do the relationships move to Google+ or do they stay on Twitter? Or both?
And how much does this hit Google? I can't get an invitation from Google for a Google product, but I can get an invitation from Twitter?
