You can export all of your data. Made sure I had that from the get-go. When writing the importer from the other providers it's amazing how much they hide from you. Disqus doesn't even export avatar urls.
Decimal place - yeah I tend to automate things and all that is generated from some configuration. I trusted Number.toLocaleString too much :)
Schnack - thanks. One cool thing that has that I don't is localization. I have to work on that.
Edit - a fun story that should have shown me how bad the pricing model is. I was using Mapbox for a project and accidentally made 1m api calls. I still owe them a few thousand dollars.... So yeah, I am morally obligated to fix it. :D
It sounds as if there's something about Commento you're not totally happy with -- I'm curious about what that could be?
I love the simple setup and that you're focused on performance and not spying on users! If the pricing gets adjusted, I would seriously consider adding it to some of my sites. Oh, if you're not going to make it open source, then an "export" feature is crucial for me, because I despise lock-in.
