Etsy could — however — as Kickstarter has done, particularly w/r/t to hardware products — limit itself to a more narrow and carefully regulated set of goods. Even as the crowdfunding world has grown, Kickstarter has maintained it's reputation and growth by sticking closely to a set of arts-oriented values. It leaves the drivel to platforms like IndieGoGo — and doesn't stray too far from it's creative core, by banning charitable projects.

I suppose you could say that that limits their growth — but it also keeps em' awesome.
