If you want your web site visitors tweet your own message there is a much better way than tell them to copy and paste it on their twitter home page. You may make a great looking link to click. When they will click it they will be redirected to twitter with your message pasted in their "What are you doing?" message box. Of course you can not trick them to tweet whatever you want as they will still have to click "update" button.
