Yeah i noticed that tonight and its showing in the toolbar too, plus the PR bar is smaller, maybe to take our attention off the crazy green stuff.
Exactly, Gogle went overboard on this one Now competitors can have people post nasty comments on our sidewiki without or control. You will Notice there is no opt out feature so people can comment on your site if you like it or not. Here is some info that Danny Sullivan posted back in September. http://searchengineland.com/google-sidewiki-allows-anyone-to-comment-about-any-site-26420
I was amazed to find out SideWiki has been around for so long. I just started getting into it and find it very interesting... In fact it could be a bit of a game changer for a lot of websites. However, I agree with barre tire, the ability for a community to form around a website without direct administration is scary. If you do a search for 'google sidewiki problems' you can find alot of people that have had their website's sidewiki abused and spammed, and the site owners feel helpless on how to get rid of it.
