Why not to use a pop-up window

If you're using a pop-up window on your website, you're doing it wrong.
It's akin to using nested tables for display, fer chrissakes!

Reasons why it's wrong:

• It's a poor user experience because the user doesn't get any of the usual browser functionality in the pop-up window, like the back button or the icon that tells you the page is loading.
• I'm sure I'll think of some more later
