Socialite.js is a neat little tool that solves a very real problem—loading up a zillion social sharing buttons slows down your site. Not so with Socialite:
Socialite provides a very easy way to implement and activate a plethora of social sharing buttons — any time you wish. On document load, on article hover, on any event!
If you’re selling your soul, you may as well do it asynchronously. Socialite won’t cause document rendering to hang while waiting for 50kb of social media.
