Does this mean that we need to periodically rebuild the database to keep it from getting too large? Or will OF occasionally do a rebuild on its own? I noticed my database (.ofocus file) had grown to "19 MB on disk (264,474 bytes)", but then a rebuild took it down to "832 KB (18,664 bytes)", using the Finder's Get Info command. After a rebuild, it takes me about 10 days to get back up in the >10 MB size range.

I suspect that these ballooning file sizes are what made transfers to my .Mac iDisk so slow; I'm now using a USB flash drive to carry the file between machines.
