Question: would people tolerate a 'Proof of work' for email? Requires a delay of, say, 30 seconds? Tolerable?
@ColinTheMathmo I would consider a delay in email a feature, not a bug. People seem to confuse email with instant messaging. Email is supposed to be asynchronous. I guess some instant messaging tools are also supposed to be asynch, but apparently everything should be like SMS. #getofmylawn
