I saw the post on my wife's Facebook feed, signed the petition and shared it to my Facebook feed. And someone read it and signed it themselves. It was effortless and the tracking wasn't creepy. This is a great follow-up email I received a few hours later. Nicely done, Change.org.
By the way, you should sign the petition, too. Kraft sells this same product in other countries without these unnecessary dyes (because they're banned). You're getting charged extra for food coloring (that's not good for you) and for what?
