In Dec 09, Google introduced the "orkut share" bookmarklet to share any content on the web that you like. With "orkut share", every time you see an interesting page, photo, video, or virtually any content on the web, all you need to do is click a "share" button and your friends on orkut will see it.
You can also let people share your webpage or blog on orkut. Just add "orkut share" buttons on your pages.
