Like the tool. But aside from just sharing the url of the page or the customized URL.. Wouldn't it make sense to also be able to add some text/comment? Like if sharing on twitter / facebook, it just drops in the URL.. thats fine, but wouldn't it be more practical have the url and comment / text. For example, Twitter, could have shortenurl and Check out this video/image/blog post/etc.
