This plugin makes syndicating your content to social networks easy. While other plugins have 100s of available networks you can connect to, this plugin makes it easy to post share buttons for the 4 big networks: Facebook, Twitter, Google+, and LinkedIn. Who uses Ying Yang and Bamalamadingdong anyway? Once activated, you will see a series of social plugins at the bottom of each post allowing your site visitors to quickly and easily post the content on your site to their profiles on these networks.
The plugin has a robust options panel allowing you to pick and choose which networks to support. You can also customize the Facebook and Twitter plugins in the exact same was as you would be able to if you were pulling the plugin code directly from the supporting website.

<ul>
<li>Choice of any or all of the following networks: Twitter, Facebook, Google+, and LinkedIn</li>

Note: The Facebook “Send” button, when activated, sometimes disappears on some browsers after a momentary display. This seems to be connected to a Facebook bug documented here: <a href="https://developers.facebook.com/bugs/299191993489218?browse=search_4f9eab716e1110276007093" rel="nofollow ugc">Facebook</a>.
