I never thought it would happen, but I was asked by a client to add a Twitter widget to SharePoint. I never really thought of this before, but ultimatley it is really simple. In fact I did it on the fly in the middle of the demo.
So here it is in case you want to add Twitter to MOSS 2007 at some point
Go here while logged into to your Twitter account – http://twitter.com/widgets/
Select "My Website" and choose to display your "Profile Widget"
On the next page make any changes you want then click next.
Copy the code and go to SharePoint. Add a Content Editor Web Part and past the code into the "Source Code." That is it. Very simple.
