No, my review was honest. I liked Map Bookmarks, and I haven't used the Driving Directions feature (which we actually cut from version 2). As you point out, I use my standard nick name for my reviews. A Google search for the word andrewljohnson is dominated by me, so when the other poster suggested I would be mortified at being found out... clearly not.
Apple doesn't seem to have a policy on self-reviews, but I'd assume that their feeling is anything goes since they know about companies hiring firms to write reviews and don't do anything about it.
