Mixx, a social news startup from McLean, VA which announced its first round funding in October, has now added an interesting strategic investor: Los Angeles Times, part of the the hopefully-soon-to-be-private Tribune. Mixx is a bit like Digg, though for non-geeks, and LAT will now integrate the service within its website: Mixx buttons will show up o each LAT story, and LAT’s stories will also be syndicated within Mixx’ site/service.

Mixx sports a number of established media veterans among its ranks: CEO and founder Chris McGill was formerly at USA Today and Yahoo (NSDQ: YHOO) while board members include former AP chairman Burl Osborne and former Yahoo VP Dave Mandelbrot.
