If you operate a website, even just a personal blog (and I know you all do – even if it's just a blogspot.com blog, or a livejournal, or a flickr account) I strongly suggest that you read this link, and email the suggested address. Phorm is a gross invasion of our privacy, but it won't work if thousands and thousands of sites opt out if it. So opt out. All of you.
I say again: shut up about your jetpack and read this.
