From what I've read and inferred from various places, the number of tickets available for the virtual line is a small fraction of the number available on the live line. Like, maybe, 80% of the tickets are at the Delacorte, and only 20% set aside for the virtual.
I'm not saying these are actual numbers, just using them as an example. But that would explain why most people seem not to win the virtual lottery.
I also noticed several enterprising people on Craigslist offering to line-sit and obtain tickets for you, for a fee. Ah, the entrepeneurial spirit!
Sarcasm is an allergic reaction to stupid people.
