I have been using Addthis bookmarking widget on quite a few of my sites. I don’t know how many visitors have used it to bookmark my sites, but I have to say that compared to the other similar bookmarking widgets, this is one of the most lightweight and versatile tool I have ever seen. And another thing I like about them is that you would never get a broken URL for any social bookmarking site you choose.
