I used to use the Share and Follow plugin for social icon display, but support for it (at least on the repository) has ceased. I really liked the fixed tab on the side of the page that Share and Follow provided. My solution as a replacement is The Social Share Toolkit. It has options to choose from a broad range of social sites, lets you provide your own icons (or use theirs) and even provides shortcode to add icons in non-conventional places.

I have created Social Sharing Toolkit Sidetab, an addon that produces a new widget area that is fixed on the right side of the page to display a vertical “stack” of follow icons (ala Share and Follow).

Problem Solved.
