Burggit has a Sharkey instance at dill.burggit.moe. It’s sort of “replacing” the Lemmy instance here. the fact that some users here seem unaware of this and instead think that the entirety of Burggit is shutting down, makes me think there should be some prominent banner or pinned post clarifying in the title.
You already have a Pawoo account, so it’s the same kind of application as Mastodon, with a timeline of posts. if does have a different UI though.
