Sort of a sub-thread to the NPR Intern thing, but I keep seeing people complain about how hard it is to support the music you love, and how easy it is to just fire up YouTube and Spotify and listen how you want, when you want (and if you pay premium, wherever you want).
I saw some similar 'tip jar' ideas going around for websites and web content, which tied in with Facebook's like button, could make a lot of sense - if say you had credit on your Facebook, and everytime you clicked like, you donated say 10p to the creator of the content. Would make a lot of sense on Soundcloud and Spotify and YouTube and maybe even on DiS reviews (I mean, if you wanted to buy Hayden who wrote that Reverend review yesterday a pint or give him a financial high-five, it wouldn't be easy to do via the website...)
Renumeration isn't easy, and often even finding band merch isn't as simple as it could be. And for all the talk of weening people off of Piracy that you hear from services like Spotify, you see very little movement toward shoving deluxe editions and merch and tickets in people's faces. I'm sure that will change (but I hope it doesn't end up looking like the NME website)
