I usually scan through. I rarely use the live feed. I normally lurk on the same sections since that's where the most interesting questions are. I've never answered a break up and divorce or marriage question.
I have my gag routine. I come here, check out all of my notifications. Then I go to feed --> questions. Then I middle mouse click open in separate tabs all the questions asked within the last 5 or 10 minutes (depending on what day it is). Then I try to answer said questions. Once I answer them, I refresh the questions tabs and open all the questions that were asked while I was answering the previous ones. Rinse and repeat until no new question has been asked.
