I'm 36, and my interests vary so much that I find having a community of smart people discussing multiple topics nice in and of itself. Most communities are either full of not-smart people or much more specialized. Of course, I still read both other types of communities, so perhaps I just have too much free time these days.
I'm 36, and have been on the interwebs long enough to know where to find the other non-tech bits of interest.
I prefer just the facts here.
