I had a problem getting these feeds (mentioned around the 20:00 mark) to load properly in the app as described later in this demo series. I was able to make it work by changing all atom.aspx URLs to rss.aspx. Other than that, great series. I look forward to using what I learned here in the very near future.
I write C#, VB, T-Sql and dabble in a bunch of others as well.
