@andresmh@hci.social Yes, the main difference is that the network is at best secondary and possibly just nonexistent. For example, you can follow on TikTok, but it's not a main driver of the FYP.

In theory, you can algorithmically rank any threaded design: spaces (Reddit), network (FB/Insta feed), or commons (TikTok FYP). Commons-based designs have few options beyond algorithmic ranking, though.

And yeah, when there's a bounded space, paid subscriptions to gain access is a clear metaphor.
