OK honesty time here. If I was to build this app again it would likely take me maybe 15 minutes, or in other words it would take me longer to do the background and graphics then the app itself. For the GHI related stuff I used their RSS feeds and while I would have liked to do more with them, I understand that GHI controls the ShowCase stuff and the other feeds are more dependent on what folks enter (or don’t), so the ShowCase section in the app looks better then the other sections. There is my Gadgeteer Channel from YouTube and a search on YouTube for the other sections. The More section is a little more interesting as its cloud based and I can add/edit/delete items in that list as needed.
Now how do you write a Windows Phone app in 15 minutes, I used http://appstudio.windowsphone.com so there isn’t actually any coding. This came about after I got Jan Hannemann who is our local Nokia Developer Ambassador, to do a User Group Presentation in Calgary ( http://www.meetup.com/Calgary-net-User-Group/events/164646722/ ) on this tool and I thought it would be perfect for an informational app for Gadgeteer, so it happened. Now Windows Phone apps are very much on my radar as I wrote apps for Windows Mobile years ago and some were even available in the app store (others required 3 or even better 7 letter agency security clearances etc )
But check out the http://appstudio.windowsphone.com tool as for some apps its a workable solution.
