I submitted my review of of the Unicomp Customizer (http://hardware.slashdot.org/story/08/05/29/1334258/Review-o...) years ago, and I think that day remains the most traffic I've ever gotten. Granted, it's a generic Wordpress.com blog and thus not susceptible to Slashdotting, but I still remember looking at the traffic spike and going, "Wow."
