Next week’s big conference in L.A., Marketplaces 2009, is likely to be something of a game changer. Great speakers, great signup list, great city and venue … and very hot topics.

This time we’ve tinkered with the formula, a bit. In addition to talking with the speakers on our podium, we’ve asked many of them to participate in “Green Beer Speakeasies”  — a chance to informally talk with them among other interested peers. (And yes, we do expect to find some green beer for everyone, in honor of St. Pat’s.)

Haven’t signed up yet? You can register here. And our discount rates are still good at The Century Plaza, in the heart of Century City.

Here’s a handy guide to the speakers. Everyone’s coming!
