Why does he even bother bringing Wave into this? As a Googler he should know that Wave was never meant to be a social network. It didn't even have the subscribe of 'friends', it was an attempt to create a new kind of Email. He worked at Google but didn't realize that all that innovation, be it GMail, Android, Chrome, Search, Maps, Google Car, etc was paid for by ads?
