QUESTION
I see a new logo with CA at youtube.com. Does anyone know what it means?
ANSWER
That is due to you accessing the Canadian locale of the site.
If you go to http://www.youtube.ca you'll be redirected to http://www.youtube.com/?gl=CA with the CA in the logo.
If you accidentally got to that version you can just visit http://www.youtube.com/?gl=US and it will give you the US version.
The two letters signify the two-character country code for countries. A complete listing can be found here
