What is this thread all about?
Just a place for general discussion. A place to unload whats on your mind and talk about anything - personal, health, help needed, achievements, daily highs and daily lows, theories, predictions and what have you.
Does not need to be Q related.
I suppose the mods are some of the top users here, though you can click on anyone's name and see how long they've been here and how many points they have for posts or comments. That's a good way to gauge their usage.
No idea on the population. Some people who use the site don't even have accounts, they just read and lurk.
