I've been increasingly sceptical of things from Google, because of their track record. That includes the usual losing interest, as well as general people avoidance. Quite simply they are not a safe bet. That all said it takes time for things to become mainstream. See the Joel article: "Good Software Takes Ten Years" http://www.joelonsoftware.com/articles/fog0000000017.html http://www.joelonsoftware.com/articles/fog0000000017.html Go dates from 2007, and is currently 8 years old, and is heading into the mainstream. Dart is about 3 years old - it will take more time plus a non-typical Google track record to get there, if it ever does.
