I'm not certain what the OP meant, but I believe that Google acquiring Twitter would be a huge step forward for G+. The biggest problem that G+ has is that, while lots of people may have accounts, no one actually uses their account. If I could integrate Twitter and post to my G+, I would do so in a heartbeat. You would suddenly be taking a great deal of content from Twitter and cross-publishing it onto G+ where others could comment on it, share it, etc.
I think that it could make G+ a real player in social media.
