Social plugin to attach to each post on category page

Here's an example: http://www.buzzfeed.com/whitneyjefferson/naked-golfing-on-the-bachelorette#.sxg7PzdLA
You can see as you scroll down the socials become visible on the left of each post on their category page. Does anyone know of a plugin that could easily do this? I know of many that can put a single set on a page, but I'm trying to accomplish having a set over each post listed on the category/archive pages.
