How about blocking StumbleUpon and Delicious?

Edit Subject

Ghostery recognizes certain items as StumbleUpon Widgets. Do you have any examples where StumbleUpon is not being detected?

There doesn't appear to be much Ghostery can do with the current (AVOS) incarnation of Delicious. There are still a few sites out there using a previous generation's "linkroll" code — which is undocumented, unsupported, and mostly broken and useless. Example: www.seobythesea.com

Did I miss something? Please provide links to web pages you think Ghostery should find interesting.
