Remember the shit-fest that went down with FT vs Chess Club? A lot of redditors were talking about issues, and one thing that I saw was that the new ones would say "this the first cast I watched..."
Well how about getting the tf.tv casters, or even the eXtv casters to low end games, and even small community tournaments, and while waiting, they could talk about the game mode's and what's involved. Have those casters post something on reddit, and we just up vote the bloody hell out of it. It'll involve more communities & even help grow a bit.
Just a suggestion though.

Keep in mind they are for real beginners. We never made it to demo. I helped in writing the scout one, I am to blame for all that cheese :[
Could also bring this back using the tf.tv youtube, and even post articles about it. Having a main class players, b4nny for example, talk about demo. While having one main over all player talk about mids/chokes/pushes, as a team. Again, another suggestion .-.
