I am a little bit surprise that so many people still watch ads on the net despite the fact that ad-blocking browser extensions like AdBlock Plus are widely available. Do they think that it is unfair to use a resource without supporting its business model, or they are just unaware that ad blockers exist? The latter is more likely because a lot more people are interesting in distributing ads than distributing tools to remove ads.
p.s. hulu vs youtube would be a good "technology battle" exercise.
