Wow. This blows my mind. I have to beg people to email me instead of trying to IM me, talk to me, or (God forbid) send me a Facebook message.

FTFA: "You can do something as simple as calling people instead of e-mailing them. If you work on the same floor, you can even walk over to their desks and talk to them!"

Interesting. When I'm hard at work coding, I really don't want to be interrupted. (See Peopleware.) If you need something from me, email me.

Email allows me to respond at my leisure (which is fairly often, but not while I'm in the zone, please). Email also allows me to keep a searchable record of what is said (IM has logs, but most of everything is in email). Lastly, email is my task list and if you communicate something to me in a different way, I just have to send myself an email.
