I used to like this plugin, despite the fact that some of the settings just didn't fit right around content. The latest version, however, is a deal killer. I deactivated it for two main reasons. One is because on IE some of the settings gave tons of script errors, including access denied errors to like.php and other files. The other reason is because on every page where I checked the option to hide AddThis, it added about addthis_exclude custom fields. Even though it is disabled they are all still there and I have to go through each page manually and delete them.
