Facebook announced they are pushing out a new style for their Like & Share buttons across the web. I noticed it on this site a few days ago, they are blue and they really stood out from the original look.
Today, we're introducing a new design for both Like and Share to help people share more great content across the web. We're already seeing a favorable increase in Likes and Shares with the new design and will be rolling these buttons out to everyone in the coming weeks.
Sites, like this one, will be automatically upgraded to the new design.
Here are pictures of the new design:
