i somehow stumbled upon utterances today at lunch. (i think someone had it forked on their github page).
no matter how i found it, i still decided to add it to my blog here with bashblog. utterances is a commenting system that leverages github issues. so, for example a comment on a post shows up on github like this.
now we just need to figure out if it can be pointed at a gitea instance like tildegit. might be time for a PR!
