I have recently been glued to my screen watching some of the awesome presentations that were shown at the recent PDC 2010. There were some really amazing presentations and one of them really caught my eye. It was a talk about the power of ODATA and the support that Microsoft are building into Visual Studio for it. The presentation was entitled "Inside Some of The Top OData Services" by Pablo Castro. You should still be able to stream the presentation on the PDC player.
