I have recently graduated from St Catherine's college, Oxford and when I'm not working in small/medium sized startups, I spend all my time fiddling with web projects, particularly around emergent behavoir (ants, boids, etc...). I am still very much a novice when it comes to html/css/javascript and it's frameworks, so have made heavy use of and will continue to make heavy use of stack overflow.
I will admit, Twitter's a bit of a dead space for me though Github is (slightly) more active.
