Earlier quoted context omitted.
Mastodon and the Fediverse have often been advertised as "microblogging" tools, and the post length is mainly around the same as one would see on Twitter. That is a big difference from old-time message boards, where longform text was welcome and normal. (Even if the Fediverse does support long post lengths, that matters little if the community has not embraced it.)
writefreely has a better UI for reading long form posts and is quite popular among the academic communities on the fediverse. personally I host a gitea server and link to my longer documentation on my federated account. that gives me a bit more freedom to edit the content and easier to reference. matrix servers are also great for hosting federated long form content.
I host a synapse homeserver, and feel like I’m not using it to its full potential.
