I have an extension in my Safari browser that puts a little Twitter icon next to my URL bar. I simply click it, and a box shows up where I can type my Tweet. It posts the tweet together with an URL of the web site I'm currently visiting. Now, is there any such thing for WordPress? I want to be able to create posts fast from sites I'm visiting. If I'm on a cool site, and click the "Post to WordPress" button, I'd like a link to be created and a way to simply write a headline and a post and click on submit. Done.
Is there such a thing?
