"...Emacs is a text editor. And it’s a lot more — sometimes too much. I know of a number of Emacs users who practically live in the editor. As I pointed out in a previous post, some users go a little overboard with the way in which they use Emacs — as a personal information manager, as a mail client, and even as a Web browser.

One way in which I use Emacs for a task other than editing is as a desktop wiki [...] The Emacs wiki mode is a simple but effective way to bring a wiki to your desktop. You have most of the features of any wiki out there, and you don’t need to install any additional software — all you need is Emacs."
