Fancy yourself an aficionado of online video? Curate your own long-playing video playlists with Embedr, a new site that links together online videos from popular video sites (including YouTube) into one embeddable video extravaganza. The service is a breeze to use: You'll need to create an account to make your own playlists, or just head to the site and enjoy some compilations (like the "Best Moments from Lost" video embedded here). Creating playlists is as simple as pasting the URL or embed code from any of the many supported sites. Like the idea? If you give it a go, share your video compilations in the comments.
