Minimal Share Buttons by Milen Petrinski – Gonzo is a very fast, private way to add social media share buttons to your site. It’s not as full-featured as the Sassy Social Share plugin which I generally favor, but it’s a good choice if you don’t need the two features that differentiate them — floating share buttons and a “social links” sidebar widget (there are other plugins for that, and many themes now support a social links menu that displays icons in a standard place on the screen).
The best reasons to use this are performance and that it doesn’t spy on your visitors.
