What social share plugin is used for wpmudev blogs?

This screen cap http://ovo.li/N86tHh shows the social share buttons on wpmudev blog.

Looking at source it seems to be coming from wpmudev floating social plugin. The info for floating social does not show any option for static positions only floating. Can floating social provide multiple types of social share bars ?

Is this plugin still the best to use or would you recommend others ?

thank you
