Like Mark McGwire’s head, ecommerce is big and getting bigger:
eMarketer estimates 87.5% of US internet users ages 14 and older, or 178.5 million people, will browse or research products online this year. Of that group, 83% will make a purchase online, for a total of 148.1 million online buyers in 2011. By 2015, 170.3 million people, or 76.3% of the online population, will make a purchase on the web.


Until today, clicking on Google’s +1 button on search results, blog posts and other places really didn’t do anything publicly. Google has now added the functionality to the +1 button that people would expect.
