Readers picked Atheist Nexus as the Best Atheist Social Networking Site of 2010. Social networking has become one of the most popular uses of the internet and it's no surprise that atheists have also taken advantage of online software to find each other. There aren't very many social networking sites specifically for atheists but Atheist Nexus seems to be the largest, so it's no surprise that they had so much popular support for Best Atheist Social Networking Site.
It's difficult to start a new, niche social networking community today because no matter how much people are interested in or passionate about some subject, it's difficult to keep up with several such sites at once. It's no surprise that people tend to limit themselves to just one or two and that usually means the big ones (like Facebook) where there are already lots of people they know.
Atheist Nexus, though, has not only persevered but has actually grown over time. The membership remains committed to the community and their support showed through in the number of votes cast for Best Atheist Social Networking Site. All of the finalists have something to offer, though, and they all do things differently so you should check them all out to see which one suits you best.
