Social Bookmarking Buttons under a single roof

I have found simple and recognizable buttons which will help visitors save and promote blog to social bookmarking services.

The name of the button is AddThis ( addthis.com), Its benefits are

Easy Bookmarking - Makes it very easy for your visitors to bookmark your website or blog, and subscribe to your feeds (support most bookmarking and feed reader services)

Social Traffic - Helps your visitors promote blog to the social bookmarking services, which will bring back more traffic to your website or blog.

Less Clutter - Saves real-estate and reduces confusion on your website. You just put one button.

Statistics - Provides valuable statistics showing what content your visitors bookmark the most on your website or blog, over various time periods

Free - All this is completely free, and will remain free.
