• ‘Forward’
• ‘CC’
• ‘BCC’
• ‘Signature’

All of these elements are carry-overs from, not only an archaic communication model, but an extremely bureaucratic one. One where high value is placed on traceability and formality. I suspect those two concepts by themselves result in higher communicatations costs, reduced message volume, and higher default priority.

Do we have a communication interface that reflects our current world? One where communication is casual, informal, cheap, and 99.9% of it is unwanted, unactionable, and otherwise unnecessary?

Email’s IMAP protocol could still support this, it’s the interface on the client side that requires the most significant updating.

And I don’t mean echoing the interoffice envelope.
