I got started with !asklemmy@lemmy.ml, just 3 posts so far. I’d like to see askhistorians & askscience communities gaining more traction.

Yes, but things can change. Stories of Mastodon and Lemmy are inspiring. When Reddit backslash happened, Lemmy was already there as a good alternative for people to switch to. So was the case of Mastodon with the Twitter exodus. It’s good that we’ve Pixelfed, it may be just a matter of time.

Stories feature is there. But I haven’t used it myself, so I can’t tell more about it.

Exactly. The questions section on their homepage says this: “Peer-to-peer broadcasting - It reduces server bandwidth overload if a video becomes viral;”.

Compared to other fediverse platforms like mastodon and lemmy, peertube will obviously have more storage requirements though. And as usual, having many small instances is always better than a small number of large instances.

Mastodon supports account migration. You can export the list of your followers and the accounts you follow as CSV and import them from another instance. But there’s no option to import posts yet.

Also, note that when you migrate all followers in the old account will get automatically unfollowed.
