This post features a list of the 30 most popular Facebook fan pages in the world, as of June 2011. It’s probably no surprise that over half of the top 100 most-liked pages are music-related. It’s probably even less surprising to see popular brands and celebrities show up on this list, such as Coca-Cola, Starbucks, Lady Gaga, Megan Fox and Justin Bieber. The top Facebook Pages will inevitably continue to grow, but the graphical design and software complexity of these pages will also continue to increase, creating new challenges and opportunities for web designers. It took us a really long time to choose which Megan Fox picture to go with as the featured image for this article, hopefully we made a good choice!
