/jp/ - Otaku Culture

So how many denpa artists have there been? We all know the scene has always been pretty small, but what are the numbers? Personally I have works from some ~80 different labels, then add inn another 50~100 from the "Denpa Thread" and "RTL" packages, getting a total of some 150~200. Let's say /jp/ only hears about the more popular artists, then the total could be some 400~600 maybe?
I get the impression the scene is dominated by relatively few (10~20) big names, with little attention for others, at least here. Though if one actually wanders around Comiket and M3, then maybe things are different? At least within the resources I have, there seem to be a lot of artists with just 1-3 releases, before they either dissapear or their work stops making it overseas.
