We've got several teachers adding the stock twitter widget to their courses as a block, and the code for the widget seems to be conflicting with YUI...which seems weird because YUI seems to be nicely namespaced. They are just pasting two script tags right into the block.
Here's the twitter widget they are using: http://twitter.com/about/resources/widgets/widget_search
Anyone experiencing this same problem / know any solutions? Let me know if there's a better forum for this problem.
