FYI for any Ghostery plugin users on Firefox/Chrome: HelloBar is blocked by Ghostery out-of-the-box. You'll need to temporarily turn off the plugin to view the effect in the linked article (or look at the screenshots), and any of your users using Ghostery will <i>not</i> see the bar on your site if/when you deploy.<p>Then again, I'd imagine people using Ghostery are all fully aware of the dangers of PIPA/SOPA in the first place, so perhaps it's a moot point.
