Interesting questions. On the first point, yes I think this opened an alternative way for artists to fund their projects. The crowdsale outcome of course, will be based on the merit of these projects- or at least the investors' view of it.
On the second point, possible drawback i can see is whales jumping on board once this become mainstreem. Proper planning of ico can address this though.
Thanks for taking time to answer.
And thank you for your worthy question :)
