Show HN: Open-source Disqus alternative, with hot-reloading and guest commenting

I've been working on adding lots of features to Commento, a privacy-first FOSS comments plugin that I'm using on my static-ly hosted blog.

I've submitted all my merge requests upstream, but in the meantime, here's a list of features:

- Privacy first, one click deploy to launch it on your own free heroku instance (keep it alive all day long with kaffeine (https://kaffeine.herokuapp.com/))

- WebSocket functionality to get pushed when someone makes a new comment/edits/delete and have it updated without needing to reload the page. I was particularly happy with integrating a DOM-diffing technique (morphdom) into the comment update function :)

- 11KB of javascript, perfect for keeping your website performance high

- Anonymous comments can be enabled, and guests can optionally leave their name to their comments without needing to register

- Upvotes, downvotes, permalinks, nested replies

- No adverts or any funny business

This is great. Clean. Simple. No nonsense. WebSockets is a cherry on top!
