The problem is that not everyone knows everything about 'the market'. Advertising partially solves that, but relying on your social graph is also a really good way to find out which kinds of things in the market you'd like. If I see 50 restaurants nearby, but ten of them have been +1'd by people I know and trust, that's great and helps me. And I'm happy to recommend my favourite places, books, games too. I think it's an important problem that Google (and others) are solving and it actually reduces the need for advertising. What I really hate though is facebook selling their 'likes' to appear in your feed again and again, long after you liked it. It's a lie, because it gives the impression that you're liking it again, right now, which might not be true. For example let's say you liked tiger woods, that might be news feed worthy at the time. And if someone searched for tiger woods then yes show the like as part of that information, but to put it up again at a later date, say immediately after he's caught being dishonest is misleading people and sending the wrong message. The fact that they're being paid just makes it worse. What's more they don't even show you what likes they're putting on on your behalf in your own news feed which would give you the option to unlike <x> if necessary. In short not everyone hates G+
