The idea behind Google Authorship is to link a content author with his Google+ profile. In doing so, when Google displays Search results, your Google+ photo would appear beside the description.

I would recommend following the best set of instructions for this on BlindFiveYearOld to implement rel=author. Another article explaining this is from kissmetrics on how to get your picture in search results.

Here are some Help Topics from Google.

• Author Information In Search Results
• Photos and Names in Search Results

If your ESPN3 video opens up in a popup (or a condensed window as they call it) and you don’t see the “Google Cast” option, then this article from Encosia explains how.

Step 1:
In the Popup (where there’s no Google Cast Option) Copy the URL,
http://espn.go.com/watchespn/player/_/id/1655987/size/condensed/

Step 2:
In a Google Chrome Tab (where you do have Google Cast) paste just a part of the URL
http://espn.go.com/watchespn/player/_/id/1655987/

In the Tab you should see the option to “Google Cast”. These two screenshots should explain it.

Step 2

Alternatively, there’s an option in Google Chrome that’s not available on Ubuntu (at this time) so didn’t work for me.

Right Click Window Title in the Popup (where you’re not able to Google Cast)
Select “Show As Tab”

Importing a certificate to Google Chrome is pretty simple. You just need to scroll down to find the Manage Certificates button and start the Import Certificates Wizard to finish the process. Hard to find because you don’t really notice the scroll bar.

Click the Wrench Icon => Options => Under the Hood => Scroll down to Manage Certificates
