I kind of want a Mastodon/#fediverse installation for my students. I think it would be a good way for them to collaborate and share information, not data mined by an American company AND an opportunity to explore what it means to maintain a professionalised presence online and separate out their personal connections to another account or platform.
I should discuss this with my line manager, since I think this should also have a relationship with the uni's IT services rather than my risking their ire by inappropriately using their name.
