At some point, we realized that a lot of the TEDTalk Videos featured on the site didn’t fit well with the themes used. So we switched a lot of them to youtube. Some, we just didn’t even bother with at all. Now, they’ve switched from using a Flash Player, to HTML5, which is much more easier to scale. If you scour through the site, and either notice an old embed code (using flash) for any of these videos, let us know.
