I can post six unlimited questions a day, and so can you. Please try to post as many good questions as you can think of each and every day. The site activity will only increase if people know that there's new content every hour.
I'm planning on posting at least six questions a day, and only answering them myself if they don't get any answers by the next day.
It can be difficult, but I think this site is needed, and I don't want to see it die. Just post as many questions as you can every day, and I suspect activity will go up.
