Just started using Meteor + Telescope on my site TravelMo.re and love it so far. Really easy to use, kind of a pain in the butt to deploy.
Could you elaborate on why it is a pain to deploy? I've never used Meteor but I thought one of the selling points is ease of deploy, hot code pushes, stuff like that.
Disclaimer: I think Meteor is fantastic.
Never really had an issue - I can't say the same about rails! Obviously Meteor has the advantage of being younger and so less cruft has built up, but I'd bet on it still being insanely easy to deploy 4 years from now.
The Meteor team is doing an awesome job spending the VC money on making an experience that is fantastic for devs. Major props to Geoff et al.
