@Gargron the main problem that Mastodon keeps ignoring is that most people don't want to follow random people they've never known. They want to find whoever they already know.
Profile directory is sure nice to have, but it doesn't answer the question "which of my friends are on fediverse and where".
@grishka @Gargron A few months ago I did a poll where I asked people how many of their circles here they knew in person, and more than 1/3 knew 0 of their followers and followees in person. Those who knew a majority or all was a handful.
I didn't really use Twitter much but there to I feel like for most people the majority of their networks are strangers. Tho that's an outsider observation, so don't quote me on that.
