Seems like this place is going to be growing even more, possibly exponentially. Looks like you added some mods, which tells me you might be thinking the same thing.
Idea: Add one more tab to the menu (Hot/New/Rising/Top) and call it "Newbies" or something so new people can be directed. I suggest it be a top 20 posts you think are most helpful to newcomers.
That could cut down on "hey, what's Q" "is this real?" kind of stuff, and keep the boards clean.
If you like the idea, this thread can be a place for everyone to nominate posts that could be in that list.
This is a great idea. Something to give direction to people unfamiliar with Q. You can tell by the questions asked, people need guidance. Coming in at this stage would be overwhelming.
