The author of microblog.pub made a while ago a v1 package available on sr.ht that I’m running on my yunohost.
I started upgrading it to v2 package format and once finished I’ll make it available through the catalog.
Help and suggestions are welcome!
If someone is looking for python work: the project includes a db.py that is written to use sqlite3. I guess since databases are running by default on yunohost it would be a welcome contribution to extend it by the capability to connect to one of those.
