The only problem I see are the "2 month experts". Those are the guys who are asking what a trainer is one day, and answering questions like an old pro the next.
This is very true. The same can be said about people who do have a lot of experience in many areas but think they know every thing there is to know about RC just because they're an old fart. I guess you could say "20 year know it alls". These folks are rather easy to spot when at the forum page you see their handle as the last poster of about 50% of the threads on a daily basis.
