Free, unfettered access to information is one of the great benefits of the 21st Century. However, with access comes great responsibility and the need for discipline. Social networking sites, such as Facebook, Twitter, Tumblr and Flickr, have become notorious for being sites where you can easily lose a few hours, and when you are trying to increase your productivity, the temptation of these sites can be overwhelming. Sometimes, you need to eliminate the temptation to get things done, and there are add-ons for nearly every browser that can help you temporarily turn off access to sites like Facebook.
