I love having my journal be searchable via Freefind.
It took awhile for me to figure out the best way to configure everything (and I could still make it better if I gave a rat's arse) but it does the trick, and is especially useful for me, since it gives me a tool to find and link back to previous posts...
One of the most interesting aspects, however, is looking at the search reports to see what others are looking for...
