I think this website really worths mention. The site idea goes like this. You are an artist, you have fans, they have a chance to pay you (even a small amount) every time you add new content (or every month, their choice).
If the artist has enough fans, he would have a chance to dedicate more time releasing content than fighting with life. Some might even have a chance to quit a boring job and dedicate time to making content they enjoy!
The idea seems new and not many are out there, but I hope it gets better and more people start helping making it success.
Also, if you try it, please share your experience out there. I think that success stories are equally important as failure stories, so share all!
