@Jeffro,

My personal preference is to have sharing icons located below the post content, near some of the meta data as seen on WPTavern articles. ... With Floating Social Bar, the icons are stuck at the top of the post.

It's only sensible to assume that folks would be at the bottom of the Post, before they reach for their favorite social-button. [pregnant pause; cough]

There's plenty says reality is otherwise, though. I see a lot of sites with social buttons positioned like eye-candy and paraded like flags. A clear-cut & robust class of plugins compete to best sex-up & pony-sprinkle your social buttons.

If it was about functionality, the graphical buttons wouldn't be such finely-wrought objets d'art, and social text-links would be a more common option.
