Siva Vaidhyanathan says, "MySpace is slowly installing technological restrictions that will undermine its value as a social networking site. Well bowled, Rupert! My brilliant doctoral student Alice Marwick, who studies social networking and identity online, wrote this..."
So: stuff like Slide.com, RockYou.com, and YouTube’s Flash video wrappers will no longer be able to link back to the sites if the user is using Flash 9. Generally adoption for Flash isn’t that quick — but since all users with Flash 8 currently have broken MySpace video/audio players, you can expect that to have somewhat of an effect on the adoption rate (i.e.: skyrocket).
MySpace can say all they want about wanting to protect users, but really this is about them protecting their advertising dollars. The barnacle-like secondary market sites will have to find increasingly creative techniques to launch Flash-based content within the site if they want it to spread virally..
