Tip for you back-coming or just-joining oulipians! All participation is tidal, and slow days naturally occur. But you might miss toots if you don't follow folks from this instantiation, as many lock down accounts. Go look for folks and ask to follow!
(And if "local activity" is too botful for you, don't shy from muting boring accounts. Silicon has no sorrows.)
Mastodon is a "FOSS" social sharing hub. A multi-host substitution for capitalistic platforms, it avoids risking a particular company monopolizing your communication. Pick a host that you trust — you can still talk with all hosts running Mastadon. Any individual can run a Mastodon instantiation and join in this social hub in a jiffy.
