The most visited and popular post on this blog for 2008 is "How Does Google's MyLocation Really Work". I guess 1) everyone wants more info; 2) the cell-sector video wasn't enough to convince LBS buffs; 3) maperture readers might actually think I'm onto something;  4) I might be right; 5) I might be wrong. We'll never know I guess, but hopefully someday Google will comment and tell us how they built (or bought) the database.
