In standard Twitter badges, web addresses you write in your posts are not clickable and you need to copy and paste the link in the address bar to visit them. I partly modified the Twitter html/js badge javascript code to automatically recognize the http addresses and change them to proper links.

If you want to use it, you only need to change the code of your html badger, substituting “http://twitter.com/javascripts/blogger.js” in “http://www.soccio.it/code/twitter/blogger.js“.

If you want you can also download the file and place it in another place, or just copy the code and insert it inside your html code.
Magnificent Update!
Alan Hogan made an excellent work on the original script solving a bug and also making the @user clickable as well! Now everytime you address a twit to another user, the script will automatically insert a link to the addressed user twitter page. A great applause to Alan!

The old script has been updated: if you hot-linked it, you won’t need to change anything and it will start working automatically. Otherwise download it again.
Small Update [23 August 2008]
As asked by Jimmy in a comment, the script has been modified to handle links which are written without the classic http://. Now the script also recognizes addresses starting by www. So if you post an address remember to write the www at the beginning (unless there is already a http or other protocols prefix).
This is a quick and dirty edit maybe could be improved. if you hot-linked it, you won’t need to change anything and it will start working automatically. Otherwise download it again.
