Quick update - I have enabled comments for blog posts on chambers.io. Scroll to the bottom of the page to check it out!
Comments use the giscus commenting system. The system uses GitHub Discussions as a database for comments. Comments are then loaded by the page using the GitHub API.
It does require a github account to comment, but given that this blog is mostly technical that’s probably not a barrier for most people. Don’t have an account yet? GitHub accounts are free and open to anyone, even if you don’t write code (yet!?). Learn more at github.com
Lastly, you can view all comment threads in the Discussion tab for this blog’s github repo.
