Still confused about how micropayments for content would work practically. Either you have to wait at least until the next block is produced to verify that payment has received before responding to the HTTP request, or you respond before getting paid. Even if the block period is only 10 seconds (which would result in tremendous ledger bloat), the delay would still be too long.
I think it would be like any financial product and you’d need to accept some risk that payments would fail due to default. Eventually, we can hope that transactions will be faster, most likely through some trusted payment processor and/or some kind of contract.
