As a developer and maker, one of the most important things is to ship. And as someone who is not a self-professed [insert programming language] ninja or a full-stack this or that, I can safely say that Meteor has made it much easier for me to iterate and ship. I expect that as I grow, Meteor will continue to grow as well. Excited to see Meteor get closer to 1.0.
Definitely agree with you on this one, Meteor has made code easier to deploy. Haven't used it in a while but was able to get my project off the ground in less than 20 minutes. Have recommended it to non 'full stack' friends and they have had great success too. Hopefully this project continues to improve on the road to 1.0!
Don't make Meteor sound like a toy, though, 'full stack' engineers worth their salt can do awesome things with it if they understand its inherent limitations. I ran Meteor with Redis before their official Redis implementation came out, and I used Redis pub/sub to sync in real-time between 8 different instances of Meteor in production. It rocked.
Just because a framework comes out supporting only MongoDB doesn't mean you have to use MongoDB for everything. It's still on Node.js, and it still supports NPM packages, with some small caveats.
