Here's how you can use a free Chrome extension to block social plugins from loading.
1. Go to the Antisocial page in the Chrome Web Store.
2. Click the Install button.
Here's a description of Antisocial:
"This extension blocks social plugins and widgets (hereinafter simply "widgets") from loading, as they can (and do) slow down the loading of sites that they are used on. Antisocial was born out of my annoyance at visiting sites and trying to scroll, click a link, etc., only to find that the Chrome was either locked up or slowed to a crawl as these social widgets were loading.
The following widgets are blocked: - Add This - Digg - Facebook - Google Plus - Linkedin - Meebo bar - Pinterest "Pin It" button - Po.st widgets - Reddit - ShareThis - StumbleUpon badge - Tumblr Button - Tweetmeme button - Twitter - Wibiya toolbar - VK widgets"
