you can append #bounties to a nostr post or you can post on Keet. 

There's just a lot more engagement here for things like that here than on the trad social media. A lot trad is so dead i dgaf about them anymore. Not a place to look for active participants of any kind 

 Yes I've been adding hastags on old twitter years ago as well

I'm finding its more than just posting with a hastag; its full on marketing your bounty, which is just as much work (perhaps more) than just marketing my own projects
