I use FB because my family is on their.
My feed is almost entirely not my family, but “suggested” posts, and it made me realize I really hope something becomes popular to replace FB next and my family moves there.
What type of site do you hope becomes popular on the fediverse next?
Ditto. And this could work really well when coupled with Lemmy, as wikis often have a comments section, that Lemmy could provide them.
