We dont have a functional api at the moment so the best way to add usability to witcoin is through a greasemonkey extension.
Go to http://userscripts.org
and add your script to the gallery .
You can either submit your script to witcoin personally or if you dont have a bitcoin yet I will send you a .01 payment so you can.
Submit it to the site then get .99 more as a support payment by me. If its submitted personally you get a 1 witcoin support .
Ive setup the category so even 1 upvote by someone will result in a profit for you just from votes.
