Just make a subreddit on reddit.com. People tend to think of reddit as just a community, but it's also a convenient platform tool.

There's rarely much of a reason to overthink it - many people do, however, and even create start-up as a result!

Go with what's been tested properly and proven to work to a decent degree.

Thanks for the input! I was not aware that private sub-reddits could be made.

Indeed. Fun fact, there are almost 250k sub-reddits according to http://metareddit.com/reddits/

Potluck? https://www.potluck.it/

I just tried out Potluck and it feels like the whole goal of it is to suck in your graph. It has zero content or usability until you do that. I suspect that even after you add your graph, if none of your friends are using it, it will continue to have zero content. Seems kind of the opposite of what Monocle is trying to do.

I would love a self-hosted version of this monocle.io for my group as well. Any plans to release this on github or similar?

Agree, that would be awesome!
