I chat with friends, and update progress on different projects on facebook, and I hang with my gaming websites and when the newest episode of a certain cartoon comes up (guess which) on twitter. I'm up to date with most gaming sites I follow, that's basically it for social network over the browser for me.
[edit:]
oh, and I also have an iphone-4 where I have the facebook app and twitter app to follow up on things on the go, it's a simple way to do it instead of checking all my gaming websites constantly, and chatting on the go too, with people overseas.
In other words, my dataroaming internet service have paid off well
[edit2:]
As far as technological adaptive goes I can say I'm at a fair level, I can model and texture in 3ds max and lightly program things into unreal development kit (still studying the subjects).
I am building my first computer next month, and find the tutorial videos surprisingly easy to follow, I can say I'm pretty technologically adept even though I need to fiddle with some things to get them working.
