"We&amp;#39;re not under any illusion that people refrain from running ad  blocking extensions in their browsers (though we do hope your favorite  technology site is on the whitelist). The Chrome Adblock extension  (which many of you probably use) has added a new trick that brings it up  to par with the Firefox Adblock Plus extension. It can now block  ads from loading at all, not just remove them from the rendered  page."^^<http://www.w3.org/2001/XMLSchema#string>
