Sync doesn't sync, it just adds
I've yet to find an explanation of how sync is supposed to work. But after some fits and starts, I apparently have two computers "syncing." But it doesn't really sync bookmarks; it simply adds the two sets of bookmarks, hundreds of which are duplicates. They're in folders that have the same name with the same urls bookmarked. There's just two of them.
That's not really "syncing."
