I'll believe the +1 button is taking off when Amazon condescends to put it on their pages. They currently have a facebook button, twitter button and email button but no +1. That's because their customers - mainstream people - have no idea what it is.
P.S. Just checked some other mainstream places - NYTimes has facebook, twitter and Linkedin buttons on it's articles but no +1. The Guardian has facebook, twitter and reddit, but no +1. Daily mail has just facebook. Ebay has facebook, twitter and email buttons on all it's listings, but no +1. Zappos has facebook, twitter and email buttons on it's pages - no +1.
This is being ignored by the mainstream. It's only small webmasters who are rushing to add the button to their sites.
