Google’s Search Results Get More Social; Twitter As The New Facebook “Like”

Sometimes I think social search may be one of those things that sound good in theory but don't really add a lot of value in practice.

I use Google to search for things my friends don't have answers for. I use Facebook to ask my friends about things they have answers for. I don't want my interests influencing my friend's searches, nor do I care about their input on 95% of the things I'm searching for (coding, SEO, tech news, hardware, etc)
