Read it before; read it again at your prompting. I want to see Bitcoin succeed; would it kill us to pay full nodes a tiny fee?
I don't think the fee you receive will ever cover the full cost of running the full node. Running a node is "volunteer" work, you don't expect to be paid. I think Satoshi visioned most users in the future would use SPV wallets and only businesses or those who have financial interest in bitcoin to run full nodes.
