Our Marketplaces 2009 conference in L.A. is just around the corner (March 16-18). Some great additions have just been announced: Active Network CEO Dave Alberga (our fourth keynote); Yahoo Local leader Atif Rafiq; and all the ins and outs of vertical local mobile services in a Day 3 SuperForum.

The SuperForum has a lot of highlights in and of itself, including Dinesh Moorjani, who runs mobile for IAC; Sharon Knitter, Cars.com; Walt Doyle, Where.com; Tom Kenney, Verve Wireless; Scott Dunlap, NearbyNow; Craig Hagopian, V-Enable; Nick Gee, Mobile People; and Lee Gientke, Orange Soda.

We’re also working with BIA Digital Partners Principal Gregg Johnson on a very special pre-conference session that will spell out all the best strategies for financing interactive companies in this environment — timely, no? Gregg’s the best at that.

We usually see everyone who is serious about the local and vertical space at our events. Will we see you, too? Sign up here.
