Leopard’s Spotlight: actually useful
Matt Neuburg has posted an excellent article called Spotlight Strikes Back about the primary differences in Spotlight from 10.4 to 10.5, including some tips and tricks on using the new boolean operators and so forth under 10.5. Although I’m not a particular fan of Matt’s NotLight (preferring FileSpot), his observations and advice are right on target.
Definitely a useful article to read if you use Spotlight much (for finding tagged files, for instance), although it doesn’t have anything to do with tagging specifically. (Thanks to Daring Fireball for the link.)
