Fine line there. Very small population of people that start channels with the intent of getting the most will not try to market this thing for views in some manner. YouTube has toughened up it's monetization structure, so there is a lot less pirates trying to cash in on viral vids (think all the Stevo knockoff vids).
Topic where I can see the fan benefit, but then there's that point where I've had stuff straight ripped off over the years (almost weekly) with zero credit or if there is credit without asking, it's like "oh, I gave you credit." Well, you didn't ask permission.
I hope the library grows, but the right way. Screen grabs of stuff produced by others, for example, is where I have an issue. Reposting stuff from BTN or ESPN channels takes money out of their pocket, kills their analytics and actually HURTS the sport because it takes metrics away from brands that actually can show tangible growth and look at those avenues for future investment. But that's a tangent here.
