It is sad that Hugunin isn't involved with IronPython any more. But it may be good news for the IronPython and IronRuby community that Microsoft no longer has the reins. Currently it is impossible to contribute back code, which destroys any community. Moving to a fully open model seems like a step forward.

I have two questions though. What is Microsoft's commitment to the DLR and where does the IE9 Chakra Javascript engine fit into the .NET ecosystem. Will non-DLR Javascript be Microsoft's dynamic language of choice or will it say purely in the browser?
