YouTube's Channel Card Experiment

There's a new YouTube experiment that shows a channel card when you mouse over the link to a YouTube channel. The card shows the channel's images and description, a link to the Google+ page, a subscribe button, the number of subscribers and sometimes the most recent video from that channel.

This works for search results, comments, suggested videos, homepage videos, recommended channels and more. You can find more about a YouTube channel without having to open a new page.

Sometimes YouTube also shows a list of people from your Google+ circles that subscribed to the channel:

The experiment also includes the "I'm feeling lucky" play button I've mentioned here. This time, it's placed next to the upload button. The play button creates a playlist with recommended videos.

Here's how you can enable the experiment. If you use Chrome, Firefox, Opera, Safari or Internet Explorer 8+:

1. open youtube.com in a new tab

2. load your browser's developer console:

* Chrome/Opera 15 - press Ctrl+Shift+J for Windows/Linux/ChromeOS or Command-Option-J for Mac

* Firefox - press Ctrl+Shift+K for Windows/Linux or Command-Option-K for Mac

* Opera 12 - press Ctrl+Shift+I for Windows/Linux or Command-Option-I for Mac, then click "Console"

* Safari - check this article

* Internet Explorer - press F12 and select the "Console" tab.

3. paste the following code which changes a YouTube cookie:

document.cookie="VISITOR_INFO1_LIVE=0xJL6SMMUyE; path=/; domain=.youtube.com";window.location.reload();

4. press Enter and close the console.

To go back to the regular interface, use the same instructions, but replace the code from step 3 with this one:

document.cookie="VISITOR_INFO1_LIVE=; path=/; domain=.youtube.com";window.location.reload();
