I use this handy Google Chrome extension to remove those annoying
utm (etc) tracking tokens from URLs:
FeedBurner and similar links often include Google Analytics tracking tokens in the URL’s query string. These start with the prefix “utm_” (Urchin Tracking Monitor). Facebook and Google also add click tracking identifiers to outbound URLs (“fblid” and “gclid”). They are used by the target site to report back statistics regarding the origin of the inbound link.
