Floating Social Bar plugin does sticky social buttons with lazy loading
Syed Balkhi of WP Beginner and Thomas Griffin, maker of Soliloquy, just teamed up to create Floating Social Bar. It’s a plugin that utilizes the Socialite.js script in combination with a sticky bar for displaying social sharing buttons. Socialite.js is nice because it only loads the heavy social buttons when activated by hover.
It was interesting timing, because I was looking for similarly functionality just recently with Jetpack. I tested the plugin locally just now and it seems to work as advertised.
