My argument is a bit more nuanced than that, I don't expect to drop Twitter for Google+ (unless Twitter forces the issue, of course). Instead, I expect something like the following 1. Google+ APIs are released. 2. Developers add Google+ support to their Twitter apps (the way some apps have Facebook support). Beyond directly improving their apps, developers may have some extra motivation to do this because of the state of Twitter's developer relationships. 3. Google+ support in Twitter apps will accelerate the movement of users / conversations (not developers) from Twitter to Google+ that mikecane has already documented. 4. I can't see a viable countermove that Twitter could make, so the bleeding from Twitter to Google+ will just get worse. Enough cuts like this one and the bleeding will get critical.
