The experimental homepage has a simplified layout: it only shows a long list of popular videos from various channels and categories like "news" and "music".
Here's how you can try the latest YouTube experiment. If you use Chrome, Firefox, Opera, Safari or Internet Explorer 8+, open youtube.com in a new tab, load:
* Firefox's Web Console (Ctrl+Shift+K for Windows/Linux or Command-Option-K for Mac)
* Opera's Dragonfly (Ctrl+Shift+I for Windows/Linux or Command-Option-I for Mac)
* Safari's Web Inspector (how to do that?)
* Internet Explorer's Developer Tools (press F12 and select the "console" tab)
and paste the following code, which changes a YouTube cookie:
document.cookie="VISITOR_INFO1_LIVE=eKxEWQ3xcc8; path=/; domain=.youtube.com";window.location.reload();
Then press Enter and close the console. Go to youtube.com/lohp to see the experimental interface.
