I Love YTtalk
The whole theme for this is to help get exposure for smaller channels. But for example if you came to me and said "hey, I'd like to be on your show." I wouldn't just accept that as my reason to make a video. I would check your channel out myself. If I think it's up to the standards I set then it'll get a spot. But more so I'm looking for more ideas about the show and not so much the policing of it.You need to be careful who to pick though. Every person that will propose its channel will do it for one main reason: Exposure. Some channels may be good as is, or just generic, you need to see what channels are trying to do different stuff, and need improvement, otherwise it will end up being just a tool other channels use to promote themselves
