Fair enough, though I'd say for something coming from the search company these examples are a bit weak. But more importantly, what they demonstrate is that social search is useful. While I don't think I'll be searching for "awesome things" or my dog on the Internet in any observable future, I can imagine how this could be a fun experience.

This is, however, rather different from social improving search let alone social being the next revolution in search. Searching for your dog and searching for objective information about a fruit are two very different intents and unless Google can come up with some magic to distinguish between them half of your results will be irrelevant (regardless of which one you were looking for).
