I've recently stumbled upon this awesome post by Shoban Kumar detailing the creation of a Twitter Trends web part for SharePoint 2010. I really liked the simplicity of the web part, its style and its purpose, so i contacted Shoban asking his approval to post a tutorial on how to create his web part in Silverlight.
Shoban, all the credits for the idea and design goes to you my friend!
Here is what the Silverlight counterpart of Shoban's web part looks like:
To see how the application will look like, take a look to your right ;)
The full tutorial on how to create this web part is coming soon, but in the meanwhile check out the tweets on #SharePoint :)
