For Farmers: 
1. More and more things are illegal to sell or do as a farmer (especially when it comes to meat and dairy, pasture management, integrating agroforestry, ...). I, personally, already need a way around that. 
Something like the REKO rings (facebook groups that let people order from local farms and meet at a drop off points or get deliveries) on nostr, where the farmer can selectively let people in his private selling group, could solve that. 
2. There's no clear winner in that niche of marketplaces yet (facebook maybe but it sucks for that use case in terms of UI + it censors beef and dairy)
3. Regenerative farming only outcompetes subsidized farming without a middlemen taking a cut

For Spring:
Awesome! If I can help in any way with the making people love it part -> I'd be happy to.  

 Re. farming, this sounds like a very hard to bootstrap thing, with goods being not only physical, but also with limited lifetime, requiring high local network density. Although would be an amazing learning to try and onboard your local friends/customers into some usable simple app!

Spring had a significant UI change, your feedback on the latest version would be very valuable! 

 1. Maybe I'm biased because that's the context I live in and because I mostly see my own need for this. But still, the farmers I know are often the people that feel the pain of inflation and Big Tech thievery first. Pain = incentive for change = general openness to bitcoin and nostr. 
Meat, when frozen, is actually relatively easy to ship and sell online. 

2. I'm getting an android phone next week and will start testing.
