I keep mine dated for an easier way for family to see/remember when they actually made changes. The filesystem sees updates on average maybe two days a week, and if recent changes were made only on Nov 9th and Nov 14th, it works well here to see only a Snapshot-2008-11-09 and Snapshot-2008-11-14 compared to clicking through a few dailies worth of clutter. That's the main reason I clean up duplicates (I know in byte-terms I'm just saving directory blocks and the hard-links are free). Thanks, ~ Daniel
