Finally found the pesky flat files for Blojsom. They reside in /private/var/root/blojsom-blogs/ I found them by resorting to opening the properties files one-by-one. The clue came from blojsom.properties of course.

What is interesting is I can’t go to this directory without logging in as root (su) and then when I do it shows me as being in ~/blojsom-blogs root#

I have no idea…
