DataWrangler (demonstrated at StrataConf just now) is a very useful looking tool for first, extracting data from semi-structured files and (more importantly) secondly creating a script for doing the same extract again on similar data.
Data is the new Rock & Roll, the new black, the new new, the new Beatles. Semantic markup is therefore the new Brian Epstein.
The data from Google Analytics has started to roll in, and the highlight (from a purely human point of view) is certainly the map view which shows where on Earth everybody who visits this site comes from.
