I love that the comments on some of the posts (like this one) are written by hand too!

This is actually not on handwritten.blog, but on the site of the person where I got the original idea from! Maybe I can incorporate something like this on handwritten.blog too (e.g. a way for people to send in comments via email).
https://tuhat.net has comments via email, but only when responding to a newsletter post. Then the replies are put in the authors letter inbox connected to the post. Though all comments are private to the original author.
