Tweet this - a bookmarklet to post URL to Twitter

This is my first bookmarklet.
The bookmarklet posts the current page's title and URL to Twitter. I guess many of similar bookmarklets would be found somewhere though.

Tweet this

Drag & drop the link above to your browser's bookmark toolbar.
Its code is referred to delicous's bookmarklet.
javascript:(function(){f=''+encodeURIComponent(document.title+' '+window.location.href+' ');a=function(){if(!,'_blank'))location.href=f};if(/Firefox/.test(navigator.userAgent)){setTimeout(a,0)}else{a()}})()

Thanks, delicious!
I don't know the license type of the code snippet, however. ;-)
