Dana Blakenhorn is one of the keynote speakers here at Liferay West Coast Symposium. He's probably one of the most non-Liferay speakers at this symposium giving him the perfect opportunity to express new ideas to this community of Liferay developers, partners, and users. I love these "strength of weak-ties" guests in conferences as it allows for some people in this crowd to "get it" and run with it.

The description for his talk:

Here at the Liferay West Coast Symposium, Bryan Cheung (CEO) and Paul Hinz (CMO) just announced the newest and upcoming version of the company’s Liferay Portal 6.1, as well as the developer community release of the new Liferay Marketplace. Liferay, Inc. hopes these moves represents a showing of strong new convergence of portal, web content management and modular applications for Liferay products.
