TerraI agree that the biggest issue with the growth of competitive TF2 right now is that people don't know it exists.
I believe this is one of the biggest issues, but also I wonder, if people are interested in competitive TF2. Even some pubbers know of it, but just wish not to play. Getting known is one thing, then we have to rely on getting more people interested in it. If there was a more simple guide like Terra said on the front page, it might be able to keep someone looking around there and try it out.
