I haven't once shat on it, and it isn't sight unseen, I've been playing with it since I saw this link. I think they've done an excellent job with it, and I really hope it succeeds, because I really want something like this.
But I also think briandear is fundamentally right that for this to be successful and thus useful to me for more than a short period of time, it needs to have a selling point that doesn't only appeal to computer nerds like me who know what "decentralization" even is, and care about it.
