<p>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.</p>
<p>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.</p>
<p>Default Options include:</p>
<ul>
<li>Choice of any or all of the following networks: Twitter, Facebook, Google+, and LinkedIn</li>
<li>Customization of tweet content allowing you to use to use the page title or to customize it</li>
<li>Add a Twitter user to the tweets</li>
<li>Add a hashtag to tweets</li>
<li>Include or exclude the Facebook Send button</li>
<li>Choice between Facebook verb to use (Like or Recommend)</li>
<li>Option to include default styles or leaving the styling up to you</li>
<li>Place the Social Plugins above the Post Content, below the Post Content, above and below the Post Content, or place them manually</li>
<li>Restrict the Social Plugins to just the posts, pages, or any other registered custom post type</li>
</ul>

<p>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>.</p>
<h3>Usage</h3>
<p>Simply activate the plugin and you’re all set.</p>

<h4>Social Sharing By Danny</h4>
<p>The simplest sharing links possible for Twitter, Facebook and LinkedIn.</p>
<p>Most WordPress plugins that add social sharing functionality are too ugly, heavy, complicated or poorly coded for my liking. This plugin aims to be better: simple, efficient and flexible.</p>
<h4>No script dependencies</h4>
<p>From itself, the buttons are actually plain text links which require <strong>no external scripts</strong>. It makes no sense to load over 50 kilobytes of scripts and styles for a functionality 95% of your users will not use.</p>
<h4>Simple, yet pretty and user-friendly</h4>
<p>You can have the plugin load two very small files to add icons and a pop-up functionality to the sharing links. This way, users do not have to leave your website after clicking a sharing option. Both files are optional and you are free to craft your own styles.</p>
<p><strong>Features</strong></p>
<ul>
<li>Sharing links for Twitter, Facebook and LinkedIn</li>
<li>Simple icon styles with a hover effect</li>
<li>Simple script of just 426 bytes (with no additional dependencies) which will make the various sharing links open in a pop-up window.</li>
<li>A shortcode and a template function to display the buttons anywhere you want.</li>
<li>An overridable filter to customize when and where to display the sharing links.</li>
<li>Translation ready</li>
</ul>
