On this site I try to give you a choice between watching videos on the same page. Or by jumping to YouTube or another site.
It’s faster to watch the embedded video. AND embedded YouTube videos normally do not have those annoying overlay ads.
If you’re in a hurry, just watch the embedded video.
But when you jump over to YouTube you have the option of watching a higher resolution version. You can comment. Rate videos. And see more links to related videos.
It’s nice to have a choice.
The future looks bright. YouTube and Vimeo have begun replacing “memory hog” Adobe Flash format videos with the new HTML5 standard.
The sooner that happens, the better.

I like the “popout” option because that way I don’t have to stay on your page (in google reader) or go to youtube and watch, I can pop the vid out and watch in one window, and keep going through my reader in the other.
