Async Social Sharing free WordPress plugin

Simple social sharing plugin that loads the third-party scripts asynchronously and after the page loads to improve site performance. The plugin provides settings to load any of the following sharing widgets: Twitter Facebook Google+ Linkedin Hacker News Available display options include ability to display the sharing widgets on above or below content on pages, specific custom post types or blog and archive pages. Why is Asynchronous script loading better? Asynchronous loading allows multiple files to load parallel to each other. Instead of having to wait for Twitter to respond with their script, the browser moves on and starts fetching the next request.
