A New Video Editing Feature
Mashable gives a run-down of a new feature that Youtube is providing:
"Some YouTube users may be noticing that they can now edit their videos onsite thanks to a new feature that's rolling out globally Wednesday. Using the feature will enable you to edit uploaded YouTube videos while also maintaining the same video IDs, making it possible to hold onto view counts and comments. Existing links to the video will also continue to work. All you have to do is click "Edit Video" on your video's page or on the My Videos page."
