As most of you probably know, companies like Google, Yahoo, and MSN have created their own Internet Explorer toolbars with added functionality.  Besides integrated search, one of the most used features is blocking pop-ups, an overdue feature for Internet Explorer.

My question to all of you is: How many pop-ups have you blocked? 
I recently rebuilt my machine, but I'm already up to 369 blocks.  Mr. Keller has over 1,100.  How many do you have? 

Aside: Many of you are probably asking why doesn't IE have this, and the good news is that it will with Windows XP SP2.  More details at Ars Technica including screenshots on ICF improvements, wireless UI, and blocking IE pop-ups.
