E-reader manufacturer has announced an expanded social networking platform that provides real-time feedback--the social "pulse," if you will--of the ebook you're reading.

Let's say you're engrossed in a Kobo book. At the bottom of the screen, the Kobo Pulse or dimmer depending on the amount of online buzz related to the page you're on.

To see what other Kobo users are saying about your book, tap the Pulse; thumbnails of fellow readers appear along the top of the screen. To add your thoughts on the book, tap the Page Feed icon in the .

To see more statistics about your book, including the number of people who like it, drag the Pulse Up. You can share passages with your Facebook friends and Twitter followers too.
