There was a movement in the blogging community ~15 years ago to leave positive comments on posts you like. It was an approach to conquer negative comments and a general destructive nature of online conversations. I still do it to this day. If I really like something or appreciate someone’s work, I leave a nice comment.

Hmm… interesting. I don’t understand that GitHub comment then.

Apparently not.

ActivityPub is currently not supported for self hosted setups, we’re working on getting everything working smoothly internally first before adding official support for self hosted setups!

I wanted to try WriteFreely, but their federation seems to be broken according to this ticket. And the fediverse observer shows 0 WriteFreely comments since January 2025.
