Finally! This Sweep the Sleaze article summarizes my feelings on the "Share" buttons you see all over the web - be it the Twitter / Facebook counts that we currently see or the old school Digg / Delicious buttons - they provide more headache than good.

In a medium full of advertisement and self-promotion, every unnecessary pixel of noise and “click-me!”-begging should be avoided if it can be. The less noise, the less begging, the less secondary advertisement means the easier it is to focus, and the more likely it is that people will actually read your content.

And that's just one gem of many from the article. Go read it.
