Just to reiterate what amir said, having a group and community like COM is extremely important. They encourage people to submit, and, honestly, rewards aren't given to the most popular kid in class, so to speak.
I won on my second entry, and I think it's safe to say I'm rather obscure. Delegate to them. Support them. They appreciate comedy in every possible form. And, so far as I can tell, their community is pretty welcoming.
