Heise's "Two Clicks For More Privacy" vs. Facebook

FlameWise writes: Yesterday, German technology news site Heise changed their social Like-Buttons to a two-click format. This will effectively disable unintentional automatic tracking of all page visits by third-party social sites like Facebook, Twitter or Google+. Less than 24 hours later over 500 websites have asked about the technology. Facebook is now threatening to blacklist Heise.
