This site is currently running on the latest version of Drupal 7 with some contributed modules. The big ones, and most apparent, probably being Views and Pathauto (along with Token). I've got Tagadelic for the tag cloud in the sidebar and I use the small, nifty Read more link module to slap that line at the end of the teaser rather than down in the normal links listing. I've also got Code Filter for pretty code in my posts. The site is protected from spam by Mollom. The Flickr and TripIt blocks in the sidebar are just widgets from those services put into custom blocks - no fancy modules there.
