The WordPress Social Sharing Optimization (WPSSO) plugin is a fork (aka child) of NextGEN Facebook (NGFB). They have the same author, many of the same excellent features, but WPSSO is distributed without NGFB’s social sharing buttons, and their related features (shortcodes, widgets, stylesheets, javascript caching, and url shortening). As a result, WPSSO is 20% smaller and is often preferred for websites that already have (or don’t need) a set of social sharing buttons.

Several extensions are also available for WPSSO:
