answer:They’re completely different websites. Facebook and Myspace were similar because they were ways to meet and talk with people and present yourself on a page. As for Youtube, lets say you make videos and want to reach as big an audience as possible, you go for the site with the biggest views. Maybe you’re just looking for videos instead of making them, you look on the site with the biggest amount and variety of videos. Youtube won. Also Youtube pays its users if they get a decent amount of views regularly so the main stars are not going to jump ship any time soon. You could go to Vimeo (sort of the Fluther vs Yahoo Answers) where you get a more specialised quality and a very different audience. There were other video websites around the time of Youtube’s rise, Dailymotion springs to mind, but Youtube was just much more direct it seems. It knew what it wanted to do.
