There are indeed "slow" periods or hours here. But what's weird: there are often unnamed "onlookers" or guests waiting probably for "action".
Maybe that coming Christmas time, work pressure and private life are keeping many busy, or maybe that users struggle with too many sites or are losing interest in certain themes or smaller communities.
Yes, I noted some rude or respectless answers, and I suppose that most of us have to deal with them (I got even a downvote).
And sadly enough, very few seem to have the time to answer to comments, unless they miss out answers (or late answers) to former questions.
