Unless you're a twelve-year-old showing off your Minecraft mods or your new styling tips. Then you're getting non-monetary value (friends, fun, reputation) from creating content, and you're unintentionally competing for the attention of kids and tweens that used to buy comic books and Backstreet Boys albums.

You said 'creators and consumers of niche products' which implies commercial intent to me, and we are having this discussion in the context of music publishing. You're not wrong, but I think this is a loss of focus.

Hardly. Commercial content has been challenged and displaced by non-commercial, purely cultural content like never before. Young people would rather see a goofy image macro that their friend made than some lame sitcom by old white guys in Hollywood. For the first time ever, this non-commercial content lives side by side with commercial content on massively popular portal sites like Faceebook, reddit, and YouTube.
