You can usually tell what kind of programmer someone is by their usenet or email sig. If you've got a good programmer that covers their bases, you'll get a good sig when it's viewed in a monospace font.

People who have sigs that look oddly spaced in a monospace font assume you're going to be using a newsreader or mail handler that has the exact font they were using, and that you've got your client rigged to display in something other than plain text. These people often don't make code that follows convention, and following some convention is what makes code extensionable and maintainable.

Or I'm just high. One or the other.
