#ReadAs v0.2 is now available!
This version is basically good enough to host yourself, i.e. I don't think there will be any major changes in the near future that you'll have to work around. And if you do try self-hosting, I'd love to hear what the experience was like.

I've also created a test instance here: https://readas.labs.abunchtell.com -- please test it out and let me know what you think!
