I did use one to put some of my dopey Star Wars content on my myspace page and it works well enough. Continued tweakage will only help this feature out.

Guys, I need your help! Can people please try and use the new list widget tool to put an RIA rating list on your RIA profile page, MySpace page, or Blog? To try this feature out, click on the third link in the "Actions" box on any list page. Please try different designs, and if you can, try adding an image to the widget. Please send anything that doesn't work to me!
