I can see your point. nostr has been a slow burn for me. most posts get interactions, some get comments, some get zaps. usually it is the same people but I don't mind. Once in a while I see someone new interact with me and I try to reciprocate if I find their content interesting as well.
I like the slow pace and the meaningful connections. I've been around for a while and there are lulls.
with that said, if you find that you aren't getting the interactions that you want, it means that whatever you're doing isn't resonating with people and you need to change it up. try something different and see what happens because whatever you have been doing isn't working.
