Whoa, this blew up! Here's a working demo that I just hacked together: https://adtac.github.io/commento/comment.html

Edit: sorry, I had to purge the comment list because of an update. From now on, your comment will only be alive for 30 minutes. It'll be deleted after that. This is, of course, only for the demo.

Nice, that demo loaded pretty fast even with a lot of comments :)

And I'm only using now.sh's free tier for the backend.

I was going to comment on the slightly laggy edit box. This might explain that?

I am on FireFox 53.0 on a decent Windows 10 laptop.

That is because there are over 7000 comments right now. Clearing it. Try again, it should be snappy.

How do I get notified when someone else replies my comment?
