Safari Extension: Stop sharing with Shellfish: Hide sharing buttons everywhere

If you're tire of seeing the share this on twitter, facebook, reddit, etc, etc. buttons on websites you visit, go nuclear on them with the Shellfish extension.

It removes all the big ones (twitter, faceboook, digg, google wave) and many smaller ones.

OpenBits Software is very active with the updates to this extension (which will probably break the download link above pretty soon) but you can always get the latest at their website.
