Just today during my biweekly Hotmail check I realized that Hotmail's Junk folder is the only spam dump I check every time I'm on to ensure that I haven't missed something from someone I know. (Or something from someone I knew back when I regularly used Hotmail.) No spam filter filters more non-spam than Hotmail's junk.
Or something like that. In other news, I'm happy to see Slashdot is still doing well.
