Alright guys, thanks so much for the input! I've waited a bit to see what others have to say. The whole ethos of these SE sites is to be concise. I think we should stick to the way it is.
The comment system is a great way to interact more casually while staying somewhat focused on the question/answer.
As Collin says, Twitter is of course a fab environment for "socializing".
I love the idea of having a Facebook page for casual socializing! So here it is: http://www.facebook.com/pages/Social-Sound-Design/145661758787590
Please press like so that we start building it up. You can also check on the sidebar, I added a like button there too.
ps: If someone fancies designing a sexier and more interesting profile pic both for twitter and Facebook, please let me know :-)
