Resteemed! I definitely think this is something we should get on board with. A great way to promote steem and build a stronger community. I think finding a musician would gain the most attention from other sites. However, another idea is starting a "steemit challenge" of some sort that a bunch of us as a community participate in to collectively raise money for a charity, using some sort of steemit tag like you suggested! (similar to the ice bucket challenge that went around to raise money for ALS a few years ago). We could even incorporate bitcoin in the fundraiser too--I'm new so I can't really imagine how that would work, but it's an idea! Anyway, Great post :)
