This plugin is the best social sharing plugin currently on WordPress.org...unlike Digg Digg, Sharebar and Jetpack which are very heavy on the resources and block the actual page load, Floating Social bar uses Socialite.js to load the plugins whenever they are required.
Believe me i have used various techniques of loading social media plugins...like asynchronous loading, jquery technique to delay and load, sharrre jquery plugin but never figured out how to make it work.
i had also tried using the socialite plugin but it never integrated with my site perfectly. finally wpbeginner is out with this plugin, which loads the resources only when the user is actually interested in sharing the post!!
don't even think, just got for it!! :D
