When you use social media in WordPress, it gives you a slight advantage from the rest of those that don’t use it. Facebook and Twitter when used properly in your blog, create better traffic and makes your post more interesting. With that in mind, these top 10 social WordPress themes have themes that comes pre-loaded with social media integration from websites like Facebook, Google plus, Twitter, Delicious, and many other social media.
My favorite is Revolution Magazine because it has a lot of customization options, widgets, and has a solid, intuitive look and feel.
