User's pay $x per period (or merely periodically) in exchange for some amount of currency, which they 'spend' by consuming (viewing/reading/listening too) content offered by people creating things for them to view/read/listen to. Each month the artist can convert their accumulated currency in a $y payment. The platform lives off the difference between the $x -> C -> $y ratios.
If you can reach critical mass it makes for a very interesting twist on the existing model, sort of kickstarter meets bitcoin meets ebay. One way to finesse it would be for users to 'bid' on creative projects as well so a creator could say "I can do a video about kittens, free for anyone who contributes $.5C or more to the campaign, it will cost $C for non-backers to view it once it is complete."
You set up a virtuous loop where people willing to spend are advising the creators to the things they should work on, reducing risk on the creators part, increasing satisfaction on the users part, and overall creation/consumption overall.
