It depends on how much time I have. Sometimes I am in a rush, or at work, or it’s late at night (like now) and so I need to move on, so I will just click “follow” and come back to it another time. It might be weeks later, or it might not be ever (like some of the religious questions with 100 responses, and some I know were very long – I just don’t have the time ever to read that. Or the Malaysian plane speculation questions – I feel it’s irrelevant at this point).
Sometimes I’m late to a question and find there are many responses, and so I will get to it later. Sometimes, if a topic is really fascinating, I’ll just read the last few responses, then answer, then come back to it another time and read the earlier responses along with whatever has been said since I posted.
When I ask a question, I read every response.
