I do recently asked and run through them in order like that. I'll occasionally either filter the unanswered ones out, or I'll go alllll the way to the last page of the Recently Asked and start working backwards.
I go through my live feed initially, like it's the first thing I check, because my friends on here usually ask and answer questions I also would be interested in. If I've gone through it all and it's moving along slowly, then I browse categories. And if THAT is going too slow in my preferred categories [other, sexuality, style, in that order], THEN I go to recently asked and browse through those. It really depends on the time of day and how much time I have on my hands, lol.
I loiter about the 'other' section mostly and just answer questions there. otherwise I go to 'unanswered question' and browse those. Don't find many I'm tempted to answer though, I usually don't feel like reading a small essay on someones life.
