you're not going to like this answer because it's not very actionable, but it reminds me of Costa Rica.

Emergent order.

Nostr is chaotic; most clients try to order the chaos for you. Nostrudel feels like it embraces the chaos. It's a good example of embracing the unsiloing of the web I go on and on about all the time.

Probably to a fault; I think most users would find it too chaotic, but allowing users to see the chaos is better than hiding it at this stage and for some clients for advanced users.

Like I said, not a very actionable review, it's more of an overall feeling.
