Guess it really depends on what you're in for.
If you run any kind of traffic pump site (tgp, linklist, etc)
Then you should strike down at popups whenever you can becuase your sites will only grow with bookmarks. Take a look at the hun for example, there is a reason he is the biggest dog on the porch and his traffic (while mostly bookmarks) buys tons of shit off his site day after day after day.
If you just want some quick cash and plan to go back to flippin' burgers after a while...then praise the popup god.
now for smilies:
