What is the timeline on open-source?

Only @deimos can say for certain but based on things he has said in the past and recently... some time this upcoming week is probably not unrealistic. From the HN thread:

I've mentioned this for other projects, but why not do the work in the open too? Why not just make the code public as you work on it?

As mentioned, the license is a factor, but there are a couple of other things I wanted to get done first as well. I feel that it's pretty important to have good documentation available immediately about how to get a dev version running, how things work, how to contribute, and so on. I don't want to just dump a pile of code out by itself, that's a bad experience for potential contributors.

It won't be long until it's open-sourced - a week or two at most. Before today, the site hasn't had very many users at all, and it's definitely not something I'm going to be keeping hidden/closed while I continue to develop.

and more recently here on ~:

Any updates on open sourcing? We'd love to help! Even if it's just figuring out how the systems works and writing documentation on them.

Working on it! I'm trying not to worry too much about it, I can always do more cleanup and such after it's already open-source, but I do think it's important to make it approachable with good documentation about how to get started so that people that want to contribute don't get discouraged immediately.
