Networking sites

There seem to be a huge number of social or business networking sites. I wonder who uses which, so a poll...

[Poll #958831]

No "none of the above"; is this because your particular interest here is to find out what the people using such sites are doing, rather than how many people are using them?

I guess not ticking any of the boxes equates to "none of the above".

I'm curious about relative popularity and what kind of person is using which site. I figured 'what for' would probably emerge in comments.
