On this blog I have been speaking lot about the social bookmarking icons for blogger. I have even written a couplee of articles showing how to put them in blogger blogs. I heve shown you how to add AddThis to blogger and also to put multiple icons. This new one, this time officially launched by the people behind original ShareThis plugin for WordPress, is the best of all.
you can even track your bookmarking code and save preferences with this widget. But it is still in development. Visit the official blog of ShareThis for more details and stay in touch with the rest of the development. ShareThis is available for Websites as well as Browsers.
