I could come up with a dozen ways in which Google could use their assets to do new things and potentially increase shareholder value; that doesn't mean they'll do it. pg is in a fairly unique position to tell us how Bump can add value, not just some random speculation, e.g. from myself.
What sort of confuses me is that normally he is shouting from the rooftops about how a startup changes a user's life, but that's absent. I don't get it, especially because I am bullish on Bump.
