You're right, its tricky to get the balance. Having a 'quick search' (like the traxxas boards) in the corner of each page would make it easy for people to find things in a broader forum environment.

I went for a cruise around to some of the more specific forums (RC Car Radio forum etc.) and it is a shame to see how many big fat red 0's there are in the post replies column. Most of these are questions I can answer and would have done so if they were in the general car or electric car forums.
