I can't remember the last time I ran out of notes. It was definitely very early on in my use of Nostr.
I will agree that the content variety here is limited to pretty much Bitcoin and Nost (with art, music, etc sprinkled in). But we are early and people could post different content here if they wanted. I'm guessing most of us on here have interests outside of Bitcoin and Nostr.
I'm considering putting more time into #cigar content, for example. Hopefully there are some cigar people here already, but at least there will be content for them if they do come aboard. I think that's really the solution here. People have to invest in Nostr now even if it won't immediately pay off. This includes posting various types of content and curating a follow list that pays off at some point.
