FareCast for finding best day to buy plane tickets goes public

Farecast, a site that predicts what date you should buy a plane ticket to get the best deal, has concluded its private beta and is now open to the public. I've been dreaming of a service like this for years. I hate that every time I buy a plane ticket, I'm sure I'm getting ripped off. Unfortunately, the public beta still only encompasses flights originating in Boston or Seattle.
