Shirley Broughton's dashboard

I have three blogs. Can I put a widget on each one of them?
Although each blog is different; one is a personal blog, one is about blogging, and one is about writing for eHow, I can see where each blog could benefit with such a widget as this. Is this possible?
The code did embed properly on my blog about blogging. No problem there. As far as I know the widget is working. I won't know for sure, of course until I actually record something.
