Nice Social Networking Plugin

Hey everyone, I would like to add a social networking plugin to my site that is similar to one that I saw on https://www.mashable.com. It is the one that rides the left side of the posting underneath the author photo. We have multiple authors on our site that would really find this feature handy. Can anyone help me out with the exact plugin? I have been searching for a while, and while I can find many plugins like this I’m not sure if they are the specific one. Any help would be appreciated. Thanks,

JW
