Perhaps the questions being asked are such that people aren't interested in answering. For example, why would a lot of people respond to a question about the frequency of their bowel movements?
I'm doing a very intense and difficult degree at university so I don't get to come on here as much as I would like. I do like to answer questions, however, the question has to be of interest to me. Private or personal questions I do not answer.
I was posting under Gabriel's answer to say "hi" to Gabriel. On my screen it says that my "hi" is to Gabriel. But if not, I still say "hi" to you, timothysknickers! :)
I think there are a fair few members.. but often the same ones asking and answering.. some do a lot, some do less. Of course when we ask a question we can only do so from our own perspective and interest, there's no guarantee anyone else will be interested.
