By what nefarious means did Breitbart learn of Daily Caller's unpublished Journolist story?

Time to break out Glenn Beck's chalk board, because there's a conspiracy afoot!

A little before 9 pm ET last night, Andrew Breitbart tweeted, “Whereby I formally rescind my $100k Journolist reward & wish Spencer Ackerman the very best in whatever profession he now chooses to enter.”

At 1:15 AM, The Daily Caller published an article detailing emails from Ackerman and other liberal journalists obtained from the listserv Journolist, in which they discussed how to respond to ABC News' horrendous moderation of an April 2008 presidential primary debate. Less than two hours later, Breitbart published a blog post piggy-backing off of the Caller article, which he called the “obituary” for American journalism. According to Breitbart, the story shows that "[M]ost media organizations are either complicit by participation in the treachery that is Journolist, or are guilty of sitting back and watching Alinsky warfare being waged against all that challenged the progressive orthodoxy."

We've already pointed out that this story is a whole lot of nothing. Here's my question: How did Andrew Breitbart know about the Caller story before it was published?

Is it possible that Breitbart and the Caller engaged in some sort of shadowy communications, conspiring to drive their story together in order to promote a particular point of view? Who else was involved? Tucker Carlson? Erick Erickson? Fox producers?

If this conversation took place, was it by email? Telephone? Skype?

Perhaps someone should offer some sort of hefty reward for Andrew Breitbart's email archive...
