Async Social Sharing is a free WordPress plugin designed to enhance social media integration on websites. This plugin allows users to load sharing widgets for popular platforms such as Twitter, Facebook, Google+, LinkedIn, and Hacker News asynchronously, meaning that the scripts load after the main content, improving overall site performance. It offers flexibility in widget placement, allowing them to be displayed either above or below the content, and can be customized for specific post types or archive pages.

The plugin supports WordPress versions 3.5 and above and includes features such as an option to add a Facebook Application ID and the ability to control the visibility of sharing widgets. Recent updates have addressed various bugs, improved styles, and added new functionalities, demonstrating ongoing development and support. The ability to rearrange widgets is on the wishlist for future versions, making this a promising tool for enhancing social sharing capabilities.
