I've been surfing the web and I notice that there are, relative to judo, a lot of non-black belts making instructional videos. The overwhelming majority of them seem to American (just an observation).
Is this something that is encouraged in BJJ culture? I am aware of the high standing of brown belts, but is it the case that blue and purple belts are also assumed to have enough expertise to teach independently? Most of these videos are of basic technique with maybe one thing that they do differently to make it work, as in they don't really serve a purpose when compared the high quality supplemental material out there. Teaching others is an excellent tool for learning when done under proper supervision, but I wonder what the point is other than self-promotion. It's usually harmless, but sometimes when non-experts are given the mic this happens:
Or worse, this.

Anyway, if anyone could shed some light on the subject that would be awesome. I'm gathering ideas for an article on how martial arts schools/bands promote themselves through media.
