Awesome stuff YouTube. Here are some more suggestions:

-Has the YouTube "Quick Capture" feature been updated so people can
record their video in widescreen 16:9 format? If it hasn't then it
should. Detect if the webcam supports 16:9 then record in this mode
and if the webcam doesn't support 16:9 then record in non-widescreen.

-Make videos HD 1080p because currently HD videos are only 720p.

-Upgrade YouTube streams to use the 16:9 widescreen player.
