Lately I've been thinking about how YouTube.com has blown up. It has video's on just about every blog that I have been reading. They are everywhere. I stopped by their site today to find a link to that iPod designed by Microsoft video that is on Gareth Kay's blog, and I immediately saw how they've done it. They provide you with code that you can plug into your blog that creates a player that holds the video.
They've made their website viral by helping bloggers use their content. Smart.
