I had this idea when nostr first started. I think its still valid. Discoverability is still an issue on nostr. The lack of an algo is also. The community is full of interest groups. So transparent sharing of filters that allow you to view subsets of info of the global feed may help. If I take that filter and share it, people can view the params I applied and modify to their liking or just use mine. My 2 sats anyway. I'll help provide funding for it if anyone is keen

I wrote this a while back. I don't know what relay it was posted to but was in the early days of nostr so might not be there. I'll post text anyway. "1+2 I believe we could have user created filters over the newsfeed. These filters could be shareable in the community. For example. If I'm a dog freak. I make a filter based on user follows, keywords etc. I share with everyone out there. Anyone can decide to use or not. Maybe the filter creator can charge a few sats. Don't know. But the concept of shareable filters is a way to have a transparent 'view' of the global feed."

Shareable filters of the global feed. Take a bunch of user defined params (user accounts, keywords, hashtags, media types, date etc) and allow the user to filter out the noise of global to hone in on specific topics. These topics can be shared/followed/saved and modified etc between users. Its transparent and not algo based. I think it gives power to the user to decide. Of course some will create and some will just use the filtered topic. That's OK too.
