Right now, it exists as a Github project that you can self-host, but I'll soon offer it as a paid service if you don't want to host and maintain servers on your own. (And maybe even apply to YC, who knows :))
It started out with me reading a blog post [1] and thinking "I can write Disqus tonight". And that's how it began; I had a working prototype in 24 hours (at the expense of a final exam I had in two days haha). Posted it on HN, and it blew up. And then I sat down and made it into a serious project that's now actually used by other people. I've had senior devs from huge companies (like Atlassian) contribute to the project, and I think that's amazing.
