How is Yahoo Answers different from Facebook, Twitter and other social sites?

[BREEZEY 7 (((HUGS))) for rainy days]

Is it not becoming more and more like all other social sites?
Are we not just socializing in a different way, but becoming more like those sites all the time?
I'm not saying we don't ever learn, but feel people are fooling themselves a little if they don't see this site as social. We have always had social parts.. messaging, contacts or followers, etc...
The new format is constantly telling me what everyone else is doing. I've never been on Twitter,but it sounds like what other people describe on Twitter...

Why give all the extras if you don't want people to use it for social reasons?
Good or bad... I hadn't really given it much thought. Just keep wondering how it's not social unless you refuse to use any of the features offered.
