I was going through my facebook wall, giving LIKEs for some sweet posts, as I thought, "What could be the most liked thing on facebook". A gasp, followed by a Google search, and some reading before I figured it out. It's Obama's "back-to-throne" moment that made it! If I recollect correctly, it was also the same picture, along with a 3-word tweet that read, "Four More Years" which Twitter.com announced as the Year 2012's Most re-tweeted post. Mr.President is breaking records on the internet as well!
This picture, having Obama embracing Michelle, became the most liked photo once it crossed 2.1 million.
