What confuses me the most, as a new user you get the impression nostr is a thousend different, splintered worlds that dont really know of each other.

When I tried many different clients, each client presented me a completely different timeline that seemed to have no connection to each other.

And no client had a global timeline so you can get a feel whats going on or where you are.

It felt like a 1000 different rooms. And whichever you opend a new set if people talked about a completely new set of things.

Also: My first feeling was this is not a social network, but a network to talk about bitcoin. And nostr. A single theme network.

I like the protocol and I kinda like Crypto, but did not know what to do with nostr. It felt so shattered and without a general population.

For me the most important feature would be a global timeline of posts that are currently gaining traction. 

 Yes, I believe this is a feature not a  bug. People who use Twitter also will use Facebook/Gab/etc. Think of client as no different
