The idea of Dart is great - but the 'Google' brand attached to it is very worrying. Dart feels like exactly the type of service that Google will just drop in the future if it doesn't get popular quickly enough, and with only Google supporting it, that makes any code written it in a huge risk. Google's track record is the single clear problem facing Dart at present. Personally, I've been holding off on Dart for exactly that reason.
I have no idea how Google could get around that - maybe a written promise to provide support for Dart for X years?
EDIT: Another similar worry: if Dart really does take off, will Google not just drop support for other browsers besides Chrome from stock Dart?
