Up until today, I have been using the ShareThis plug-in with WP 3.1.1. However, a few days ago it stopped working for some reason. So, after sending off an email to the ShareThis folks, I decided to search for a replacement. That is when I discovered Sharedaddy.
To say the least, Sharedaddy is much easier to configure than ShareThis, particularly when it comes to adding new services that are not included in the default set. All you need to add are the service name, the URL to the service, and a URL for the service icon, and you are set. Furthermore, the parameters for each service can easily be edited via a pull-down menu.
The only problem I am currently having is a long space occurring right before the Digg icon, as well as a space after the Facebook button when I use it in Like mode. Hopefully, I will figure out what the problem is soon. Perhaps just rearranging the buttons in a different order will fix it.
Anyway, I really like this plug-in. Thanks to everyone who has been involved in its development.
Oh, BTW, I am using the standalone version of the plug-in and not Jetpack, being as I really don't want or need all of the plug-ins that are included in Jetpack.
