Would also check out postatic.com - there are quite a few startup-related communities on it already

We used telesc.pe. It's a great open source project. For this initial version of Bootstrappers.io, the site is basically what you get out if the box from telesc.pe. Major props to the makers of this open source project.

Looks like Telescope (http://www.telesc.pe/), a Meteor framework for building HN-style community sites.

Looks like it is built on Meteor.js. Has anyone used Meteor.js in production? What are some of the cons to watch out for?

There's quite a few production Meteor apps. One of my favorites is https://respond.ly.

There are a few more examples here: https://www.meteor.com/gallery (although that page seems a little out of date)

http://spotting.meteor.com/ by design will be more up to date.

We use meteorjs in production. Check out https://vida.io.
