Extremely common these days, so many people will go for it. And for some it can be a way to break in. Incredible marketing. Not only are they getting an ad cut for free, the people who are looking at this just because they want to edit are now part of their advertising reach as an addition to what they would already get.
Too bad you have to edit in the crappy Flash version of Adobe Premiere Express. I cut together an edit but to the laggy and choppy nature of editing in a Flash program, my "timed edits" fell short.
Oh well, I was exporting another project at that moment so I had some time to kill anyway!
