Sorry if I’m a little late but I saw this topic some time ago and now it has a lot of useful content I was looking for a hugo site with webmentions to have as an example as I want to implement them on my site.
But first I want to ask you about your twitter interaction buttons since I was looking to have something similar (Show a tweet conversation thread) to replace comments but your solution is way better and cleaner. I went to look your site code but I still don’t have very clear your posting process, do you have to tweet and then copy the tweet ID and paste it on the post front-matter to make it work or is a more automatic process.
Maybe as a webmention it gets the id or I’m totally confused?
