We recently joined, and then 3 months later withdrew from, the US Pod. We were lending twice as many books as we were borrowing, and since it's reciprocal, it was a net cost for us when you include the shipping costs. We would want to join again, if there was a load balancing function that reprioritized lenders based on who was a net lender vs a net borrower. It would not need to be perfectly equal; maybe a quarterly review and adjustment. The current load balancing as I understand it only balances per day, which was not working for us. Thanks for considering.
