Hi meteor.com team. I've scanned the home page and even looked at some other links on the site. I still don't know what this does. Is it a javascript library? Or template maker? A project packager? I have a lot to do and very little time. Can you make a quick video that describes why I should use Meteor and what it does for me? Thanks!
It is a full stack web framework, where you write in 100% JavaScript on the client and server, sharing much of the code with isomorphic APIs. It is not meant to be used on top of Rails, but rather as a full replacement for the combination of, say, Rails+Ember.
