Not to douse a fire, but enjoy that "ground floor" feeling over at Terracaching.  I joined out of curiosity 3 months ago and have seen the total number of caches in Arizona jump from 0 to 2 in three months.  Maybe soon that'll jump from 2 to (2 + powertrail), but there's nothing on that site to interest me.  It can go in the pile with Navicache, the Betamax, and the Pet Rock.
