yeah, i agree, sport is maybe near among the next most common interests here

diet and fitness are big on the margin, and sport is just over the other side of it, as i see it

really it's just a matter of building tools that enable small scale sports associations and hobbyist clubs to build out their own infra, and off it goes, that's how i see it

it reminds me of the old days when i was a tech, helping small business people run their tech infra to enable their business, that was a staple of my work... that's still important, and i think something that nostr can do too but it's really just a matter of finding where there is enough interest and money to get it to the point where it starts to snowball
