Alan, in Ohio, we have laws about talking on cell phones and driving. Now, I am not certain about you Texans, with all your seceding from the US talk and supporting Sarah Palin and all those other Texan things, but I have a feeling that driving and recording yourself for a vidcast should probably be against the law.
I have said it a thousand times. Simply having RP in the server will immediately turn away a huge number of people. They will assume 'well, thats not for me' and go somewhere else. Generally, those types are less mature, younger folk, especially since RP was a lot more popular 'back in the day' with table top. While age =/= maturity, it certainly helps. (*Note* I am not saying you guys are not mature. I am saying the general public is. I do not bite my thumb at thee. )
Also, I think the 'evil' faction isn't neccesarily the case. Like a lot of people, when I was first looking at wow, I was thinking 'I could be the typical, goody too shoe human knight or elven archer... or I could be a badass orc warrior covered in spikes or a freaking minotaur carrying a totem pole! Horde it is!' Depending on who has better looking gear can really affect that, I think.
