The second Highest traffic of Mashable Blog comes from Facebook after the Twitter. So, today while i was watching my updates over my Facebook status i found a recent update of Mashable on its page (having 40K+ Followers). The update was not its usual update because today the link was not to its post but a link to the Feedburner's Email Subscription.
why it pushed its Email subscription link?
They are in the need of having more email subscriber in a very short time and Facebook is the Quickest way to spread it.
Mashable is in a Challenging mood to have more subscribers than any other... So, they took the medium of the World's two Biggest Social Media for sendng the subscription link.
