I just learned about "AddThis" from Richard Byrne at Free Technology for Teachers. AddThis is a free service that lets you add a widget to your blog to allow people to easily share blog posts via Facebook, Twitter, Delicious, and more.
It was extremely easy to set up (I did it in less than 10 minutes) and you can get analytics of how many people share your blog post with others.
Try "AddThis" on your blog and try it out here and let me know how you like it.
