No tool is all good or all bad, so following on from “Email – what’s wrong with it?“, here are some of the reasons why it is useful:
Email is almost ubiquitous
… has been around a long time, so almost everyone (in a work world) knows how to use it (or thinks
they do)
… allows asynchronous communication, especially with offline workers (actually so do other technologies)
… is well-suited to notification-type communications
I’ve run out of ideas – please feel free to add comments…
