Since we are on Hacker News, it would be interesting to read something about the tech stack behind the product. After visiting your blog, I suppose you can tell, for example, how just-comments.com provides high availability with the help of AWS Kinesis, DynamoDB, Athena, etc.
By the way, this page is 404: https://just-comments.com/about.html (and some others from ToS)
Otherwise, congrats on the launch and good luck!
