I think it would be a start to let people better choose what they see. I see so much content from people I don't want to see. I would only see content from people I explicitly follow (no global bullshit, nothing from the people they follow, etc). I literally only want to see posts from those I 'follow.'

This isn't a broad solution, but it would certainly lower the amount of data my connection needs to download. Currently, well over half of what I see on Nostr is shit I don't even want to see.

I'm sure there are other preference settings (filters) that could greatly reduce data usage. This seems like low hanging fruit, but I'm not knowledgeable enough on Nostr to know for sure.
