Microsoft Max started out as an interesting technology demonstration around photos. It has now strangely added RSS to its bag of tricks.
While it is not meant to become your default feed aggregator it does have some interesting techniques to watch out for. The newspaper layout is nothing new to feed aggregators but this one is done particularly well with what I think is the best flow and layout around. It also makes use of the powerful typographic rendering of WPF (Windows Presentation Foundation.) The feed list down the left is also nicely done and useful for non-power users who only have a few subscriptions. It displays the latest bit of news in the actual subscription list.
