Adoption is a good thing but I agree it is harder to manage the feed. I have recently been going through and unfollowing a lot of people that haven’t posted for a long time and those that don’t post content that I align with or am interested in. I still have more of that clean up to do but with the recent newcomers to Nostr I have also ended up following a lot of new people.
I’ve come to the realisation that I will never see everything that people post like I did in the early days. Instead I just periodically check the profiles of the people whose notes I specifically don’t want to miss.
