I'm new to Meteor relatively. I've done a few small projects in it, and I'll be honest. It's what I was looking for over a few years.
I Love Blaze
It allows me to make sense of my front end, and use a really nice backend that just does things for me 'magically'. All things that I've done myself in NodeJS on my own, and with a lot of effort and time, and now it literally takes me minutes to make changes that might otherwise take hours or days.
A HUGE part of that is Blaze. I love it. It is so easy to pick up and start to understand. This community is amazing in helping with it's use, and it has seriously allowed me to jump into some large projects with far less time and effort, but still amazing results.
I want Meteor to Continue and Grow, but...
I want to see this project to continue forward and grow in popularity. I'm hoping that I can convince the dev team at my work (where I work as a Product Manager) to start using meteor for some of our enterprise level work.
That means, however, they'll want something fairly new and up to date, well maintained, but also something where they feel confident in it's longevity.
Not a React Fan
The Angular Train
Angular is interesting....I really didn't like the Angular 1.x stuff, and Angular 2 has made some vast improvements, but still, it's just not something I like. It seems laggy and slow, and maybe that's just my perception, but it is wha it is.
Please keep Blaze backward compatible
Whatever you do, please keep the next phase of Blaze (be it Blaze 2, Vue, or whatever) backward compatible, and as beautifully simple and powerful as it has been. If you can improve on that, then Awesome!
Finally, a big THANK YOU
To everyone who works so diligently on these amazing projects, libraries, plug-ins, frameworks, and everything Meteor - THANK YOU!!!!!!!!! You are amazing, incredible people.
