If you also use Blogger and want easier facilities for your readers to be able to share your posts with their friends very easily, I just found this code that adds a floating bar with the main social networking sites added on. There's usually the bar at the bottom of all posts anyway but I find it too small and unnoticeable, whereas this one follows the reader's scrolling up and down the page.
An easy tutorial for how to add this can be found at MyBloggerTricks, also really handy for other widgets and gadgets and tips to make your blog professional.

Hope this helps!
