If you don't know what Astoria is...
I highly recommend checking out Astoria. Pablo Castro, a major driving force behind Astoria, was on Dot Net Rocks recently, and the show provides a great introduction to Astoria. Of course, you might also want to take a look at the Astoria Team Blog.
Essentially Astoria (aka ADO.Net Data Services) provides a REST-oriented web-service over data sources which is URI based and has a limited set of standardized operations over the data. It works really well with the Entity Framework and can provide a simple and very effective way to expose EF (or other) data to AJAX clients or any consumer of a web-data service. Very cool!
