We could start a buy/sell/swap space using existing Lemmy technology, if we left the messy details for users to figure out for themselves.

Messy details add up quick, though. Payments, currencies, mailing addresses, reputation, conflict resolution, returns, scammers and spam.

But "Craigs List" solved very little of that on day one, and went on to be pretty successful.

So it's possible. happening now, I've just learned. Neat!. https://lemmy.sdf.org/c/buyselltrade
