I have heard this news The button wars heated up today as Facebook released a +2 button in response to Google?s +1 button. ?Yes, it works like Google?s button. But better. Twice as good. Clearly better. Simply better,? said Facebook CEO Mark Zuckerberg, in his signature monotone. ?Twice as much with every click.? Facebook?s +2 button pulls double duty by ?Liking? a page and also instantly sending all of your personal data directly to the owners of the page.
