If you think of Nostr as a means for computers to communicate, then the possibilities are endless. Almost every program/app that currently uses servers, could switch to using Nostr instead. And new kinds of programs/apps are possible, because Nostr is infinitely extensible.

I'm slowly working on a list of better ways to use Nostr. Notice that the first two items in the list have already been implemented.

I have more ideas in my notes. So I'm slowly adding more ideas as I search through my notes.

TikTok is a combination of YouTube and Twitter. All three of those platforms have profiles, follows, responses, and posts. What's unique about TikTok is that it only allows posts to be short videos -- similar to Twitter's prior character limit . Is there anything else that TikTok has, that Twitter and YouTube don't have?

That is true. But it did so only by increasing the rate at which content flows out of your phone. The very short videos play endlessly; it's like a firehose of content. Does any TikTok user remember anything they watch? Can they?
