As someone who's been building with Meteor since 2012, I see all of this as a good thing. It's a sign more and more people are lending their voices and opinions to Meteor's direction. As NPM support arrives with 1.3, and as a more agnostic approach to view frameworks becomes part of core, we'll continue to see more people join, because the platform will be more open towards them.
Meteor was a new platform. It's now a mature, growing platform. And it will be a successful platform if we all keep contributing.
