On my personal site I’ve been enumerating the ideas that underpin PTM in the form of an Email Manifesto. A brief excerpt is included below.

Email Hydra

Email has become the lowest common denominator for electronic communication—frequently abused and massively overused.

Much of our pain stems from asking email to do things it wasn’t meant to do. We should simply stop using email in these situations. Other problems arise when email becomes part of office politics. Our leaders should intervene when this occurs. Finally, email is just “too damn easy” and this makes us lazy. To paraphrase Abraham Maslow, “When the only tool you know how to use is email, the solution to every problem is sending another message.” Email is a useful tool, but its utility and proper use have limits!
