Webshare is another social sharing plugin but it only displays sharing links with Genericon fonts. So it’s lightweight.
<h4>Plugin usage</h4>
When you activate the plugin social sharing appears after singular post. You can drag and drop social icons in 
different order under Settings >> Webshare.

There you can choose under which post types you want social icons to appear or do you want to disable some of them.
Add Twitter username in your profile page (called Twitter Username) if you want to show it when sharing to twitter.
<h4>Theme support</h4>
If you want to set location where social sharing appears, load Genericons and handle the CSS in your theme, add this code in your themes <code>functions.php</code>.
<pre><code>/* Webshare plugin support. This means that theme handles the CSS and location of websharing already. */
add_theme_support( 'webshare', array( 'styles' => true ) );
</code></pre>
Then add this code in your themes template file where you want webshare to appear.
<pre><code><?php 
if ( function_exists( 'webshare' ) ) {
 webshare(); // Sharing icons.
}
?>
</code></pre>

Webshare

It's a good sharing plugin without "fat".
It's lean and minimal and easy to use too.
Nothing else matters.
Several (maybe) improvement that can be implemented:
- no genericons. this plugin only use several icons but uses genericons which is a large icon font library.
- no autosave on drag and drop icons. It's redundant because the settings page have a "save" button. it's probably better to save when clicking "save" instead of partially save the order and different mechanism to save other settings.
