Lately I’ve been exploring our video archives to pull out hidden gems and relive some of the important takeaways from our past conferences.

Appropos to our Deals 3D show coming up in just over two weeks, I spent some time clipping bits and pieces of Groupon CEO Andrew Mason’s keynote from our Marketplaces 2010 conference in San Diego.

Some of the discussion is familiar territory for those close to deals and group buying models. But there are some interesting insights and good moments from the always-entertaining Mason.

Of note is his discussion about working with resellers (second video), exchange with Valpak (third video) and quotes like this (on competition):

“We kind of have a way of wiggling in there and displacing people. At some point you guys will figure that out and try to kill us harder.”

Classic Mason. See the rest below. Also note, this represents a larger effort to better mine our conference content for good material to share here. Stay tuned, as they say.
