Youtube, the worlds most popular video sharing site, recieved a killer update today which allows a significantly greater degree of user customization and even some slick Google + integration.  However, jsut like the new facebook timelines, it isnt live on the new site unless you do a little tweaking.  Don's worry too much, its super easy, and here is how to do it (in Firefox and Chrome anyways):

In Firefox: Ctrl + Shift + K (Win) | Cmd + Shift + K (Mac)
In Chrome: Ctrl + Shift + J (Win) | or Cmd + Alt + J (Mac)

Then add this string of code to the developer console:  document.cookie="VISITOR_INFO1_LIVE=ST1Ti53r4fU";  -- now close your development tools and refresh, zing!!. Now you will see the new main page the folks at Google/YouTube have built for us.  Not to bad at all we would say, and a marked improvement o nthe mess that was the old YouTube.

 Here’s what’s new:

• Welcome Tour: Once you get the new design, a message will pop up, prompting you to take a tour.
• Channel Activity: Clicking a channel's name in the left-most column will bring up its recent activity in the center column.
• You can add your favorite channels to the left-most column of your new homepage.
• YouTube will suggest other channels to subscribe to based on the videos you've watched.
• Subscribe to at least three channels to fill up your column, then return to the homepage for some easy video viewing.
