Well, forward-thinking videoWTF folks, this particular answer is kind of built-in to the question. The Open Video Alliance is holding a video contest. To enter, just make a video spot explaining open video in 60 seconds or less. They will be judged by web luminaries like Jimmy Wales, Mitchell Baker, and Jesse Dylan, who will pick the best and most creative entries. One lucky winner will be headed to Austin on an expenses-paid trip to SXSW 2010 Interactive, and three runners-up will get a Flip Mino handheld video camera. The last day to submit a video is January 31, 2010. Head over to the contest page to check out the entries and submit your own video.

Still, if you aren't sure what open video is or how to use it, you know where to ask!
