Google has introduced a new Share feature in its Toolbar for Internet Explorer and Firefox. This makes it easy for you to share any page on the web with your friends over various social networks, blogs or email.
With this feature, you can just as easily share to Blogger, Delicious, Digg, Facebook, Gmail or other services.
For those you use frequently, you can save a step by adding them as buttons in the settings option in the Share menu.
Google has also integrated with more local social networks — for example, if you’re in Japan, you can share with your friends on Hatena.
