Is there a contest or something? Remember I'm new to the Shire.
I had to figure it out for myself, so I think I'll let you have the same thrill of discovery... Think round....think precious.....
If my memory is working properly, someone eventually told RWRF what it was all about, soooooo...
One of the traditions of the Hobbit Hole is the race for posts ending in 2, 3, or 4 zeroes... they've become "Precious" (or at least semi-Precious, for the double-naught posts.) Much like Smeagol's "Precious", they seem to have a strange power over the minds of Hobbits, Elves, Dwarves, and Men alike.... :)
By the way, you've chosen an auspicious time to join the group, RM, since we're coming up on a quadruple-naught Precious (30,000!)
