After doing a bit of fucking about it would appear many sources have a point. Google is trying so hard to be a social network, it's starting to move away from a search engine. It's forgetting why people use them (simply to search) and it's arrogance is blinding them in failing to notice, that they're no longer any better than the competition - as a search engine.
If they want to force shit on people and complicate something that used to be far more simple, then they have to realise people don't necessarily relent, but walk or vote with their keyboard. Google's core value (for most) was that it got results and it was simple. Neither of these are quite so true anymore - the user experience is becoming increasingly more annoying.
If Google wants to be a social network, then it'll be, at best, number 2. If it does achieve this I expect it will slowly lose market share as a search engine because people, like me, want to search for shit, not fuck with a social network that has some kind of search capability.
Think about it. Yahoo isn't a search engine, it's a portal, it chased the dream from directory to search and onto a portal. It tried to be everything to all people. It moved away from it's core, tried to expand horizontally and fucked up.
Now I know Google is a different kettle of fish, it's bigger, brainier and to a degree, knows what it's doing. The trouble is though, Google is doing a Yahoo (albeit with a different staff mentality) and chasing the dream of being all things to all people and diluting their core - Search.
Google is trying to become a social network and, I believe, it'll eventually suffer as a failed social network and a shit social search engine. Google+ is a big fuck up and, mark my words, if they continue along this path, will prove pivotal in the coming failure of Google.
