I wonder if anybody is using ShareThis widget? Do you think having one icon for users to share is more effective than having multiple icons (Facebook, twitter, digg, email)?
We used to use the AddThis widget but, once they switched it over to being a Flash-based widget, we dropped them. I don't think anyone used it @ <a href="http://www.learnitfirst.com" rel="nofollow">http://www.learnitfirst.com</a> though.
