Review my startup, colaab - A Silverlight 2 RIA for rich, real-time collaboration
tomh-: It looks very cool, I just created an account. Not sure if its usefull for me, but it is at least interesting to see a nice silverlight app. Did you build it with Blend or just Visual Studio? Personally I would pick Flex due the market share it got. But silverlight is much more enjoyable to develop with. Mainly because the adobe builder is not as good as Visual Studio and Blend.
