I love Posterous and use the bookmarklet a lot, so I thought it'd be handy to use an icon instead of the bookmarks bar.
Just hit the Posterous icon in your Google Chrome to quickly post the current page!
This extension simply provides the same functionality as the awesome Posterous bookmarklet but using an icon instead. So you can hide that bookmarks bar and get more screen space, exactly what Chrome is all about :)
Many thanks to Yogesh - https://twitter.com/redspiral - who helped me fix the extension for the latest Chrome changes.
