Readers picked The Thinking Atheist as their Favorite Atheist Facebook Page of 2011. Given how many people "like" The Thinking Atheist page on Facebook, it's not hard to understand why there would be so much popular support for voting for it as the Best Atheist Facebook Page overall. When they won this category last year they had nearly 21,000 "likes." This year, they have well over 63,000 "likes."
It would be difficult to underestimate the importance of Facebook on the internet and in people's online activities today. Having a strong Facebook presence is invaluable when it comes to activism. That's especially true for atheists who have trouble finding and meeting each other in real life.
So it's vital that atheists learn how to effectively use Facebook as well as other social media, not only for interacting with each other but also for outreach to religious theists. The better atheists make of Facebook, the better they can encourage skepticism, critical thinking, secularism, and even atheism.
If you're going to be on Facebook, you should consider networking with other atheists while you're there. The less isolated you are and feel, the better your psychological and emotional health will be. All the finalists for Favorite Atheist Facebook page are good and I recommending visiting and "liking" them all, using them to connect with others around the world.
