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.
