Meteor 1.0 www.meteor.com is finally out!
This is slick.
Fully open source under the MIT license, Meteor is what enabled apps like https://beta.workpop.com/ to get developed in record speed, or as their VC investors stated, "the most rapid prototyping, iteration and development we’ve seen from an early stage company."
But don't just take my word for it. Take theirs:
Netscape co-founder and Managing Partner of Andreeson Horowitz Marc Andreeson's: "Meteor is what we should have built in Netscape"
Facebook and Asana co-founder Dustin Moskovitz's: "Definitely something the industry needs right now."

Its nice and slick.
Well I have worked on backbone/angular frameworks earlier, and find this very easy and similar to those.
People with javascript knowledge or even without can easily learn this in hours.
Good one.
