Posterous

With this extension you can post content (images, video, text, etc) from pages to your Posterous. This is essentially a port of the Posterous bookmarklet to an extension (inspired by the Posterous for Chrome extension) and it functions in the same manner. Just click the icon for the Posterous dialog to appear, where you can choose what content from the page to use, edit it as you see fit, and then post it. Additionally you can highlight text on a page and then click the button and that text will be displayed in the dialog as a quote. As an extension, it allows the inclusion of a beautiful icon without having to fuss with editing the skin to include a custom icon so that all of your bookmarklets don't look the same. Additionally the Posterous bookmarklet does not currently work in Opera, while this does.
