I'm struggling with the idea of either making separate buyer and seller accounts for a marketplace I'm creating, OR to combine the accounts.
The main hurdle in my mind is the rarity that in this particular marketplace any buyer/seller would swap roles. However this is a catch 22, because those same rare instances where a buyer would want to buy something makes me want to combine the accounts.
Are there any hybrid solutions you can think of?
Perhaps integrating a "link accounts" feature or something...?
