- Peertube videos send a link to video over ActivityPub, but not video itself
- no E2E encryption

# Mastodon

- local timeline
- personal timeline 
- following hashtags
- no recommended posts, no sorting algorithms
- moving mastodon account from one server to another is supported (moves all your followers and accounts that you follow to the new account)
- some servers block other servers content (that have less strict moderation rules)
