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.
