What Social Sites Do You Belong To? (+ a gratuitous lolcat)

Now, on with the pwn -oops.  I mean point.

Ahem.

The sense of participating in a community has been an unexpected side-effect of blogging for me, and I’m really enjoying it.

I’d like to expand on it, to find a deeper sense of community with all you similarly tweaked minds out there. The Social Sites seem like a no-brainer, but…. the number of them is overwhelming, none seem a perfect fit, and I don’t exactly “get” the point of most of them.  

So…  I need your help : )

Which social sites do you belong to?  

What’s your reason for belonging?

And how’s that working out for you?

(I’ll show you mine if you show me yours…)
