Also, why aren't Wikis #Fediverse-enabled by default? I'd really like to follow certain articles on #Wikipedia, for example.
If you must, it could be following something like @[email protected] but interpreting the actual URL to the article like https://en.wikipedia.org/wiki/Fediverse as the actor's primary identifier would be so much better. Well, either would be better than not being able to follow at all...
