There will be a few areas. One of them will be in the point submission section. One of the really nice things that Silverlight will offer us is a cleaner way to enter submissions. Although AJAX offers ways to avoid postbacks, it pales in comparison to a Silverlight interface.
Another important aspect is in the display of your portfolio. I am aiming for a very impressive way to show off your contributions so that you can have a very cool page to show off to people displaying all of your contributions to the development community. There is also an alternate, rather unique, display of your contributions that I have planned, but I will leave that as a surprise.
