We recently got wind of ByteCaster, a site that will give you $100 and a video assignment if you submit a video that they like (around 30 seconds in length). Their intent is get some Web video content. Current topics that they are searching for videos on include dating, travel, roommates, sports, money, cars and diets, among others. ByteCaster is also running a short comedy contest (also 30 seconds)… the grand prize is $3,000, and the top 10 finalists will get an additional $3,000 in prizes.
