Keyword Assistant (KA) for iPhoto received a 9/10 MacOSXHints rating back in August 2004 as a Pick of the Week. It's been a great productivity enhancer, until iPhoto was updated past 6.0.2 -- Ken Ferry has not updated KA since then, and he designed it to limit KA's features when an iPhoto version beyond 6.0.2 was installed.
This was terrible for me, since I depended so much on KA -- I emailed Ken several times to no avail -- and then browsing VersionTracker's comments one day, I noticed this suggestion by editcandy:
Quit iPhoto -- Find your iPhoto application -- Control-click and choose Show Package Contents -- Drill through the following directories: Contents -> NetServices -> Bundles -> KeywordAssistant.NetService -> Contents -> MacOS. Open KeywordAssistant in your favorite text editor (I like Smultron). Search for the phrase: WarnForiPhotoVersionsAbove and change the version number that immediately follows to something that corresponds to your current version of iPhoto -- Good luck.Well, it works just as advertised, and I'm happily using KA with iPhoto 6.0.4. Hope some others find this useful.
