One of the biggest disadvantages of static site generators is that they are static and can’t include comments.There are multiples solutions to solve this problem. You could add a third party blog engine like Disqus, but this has the drawback of including a third-party tool with a bad privacy record in your website. Another solution would be to host an open-source alternative but this comes at the cost of a higher maintenance burden.
Having to host a database was something we wanted to avoid with a static site generator.In my opinion, a better solution is to leverage the Mastodon and Fediverse platform. Mastodon is a decentralized social network and it allows people to communicate with each other without being on the same server. It is inspired by Twitter, but instead of tweeting, you write toot.

Aside of folks who just prefer static sites, this is a great option for the next time the “upgrades” break everything, and we have to go back to HTML.
