The new Firefox extension Piggy Bank sounds like a good idea. The Semantic Web is a grand vision that has altogether lacked a sufficient implementation. Piggy Bank is designed to bring the Semantic Web to sites whether they use it or not, kicking and screaming if necessary.
Unfortunately, this implementation takes down Firefox. I would say kicking and screaming but it’s more like puts Firefox down like Rohypnol. I was just working on a blog entry when I had to quit Firefox. It started putting up an hourglass just to get an image’s properties. I looked in the Task Manager: 671MB and 55% CPU utilization for firefox.exe. Uh huh. I’ll wait for the kinks to get worked out.
Note to developer: killer apps don’t kill. It’s just a figure of speech.
