Wes talked about hobbyist developers last month... With the work I've been doing (ok, not work, but play) on Python and Avalon, I've really come to the conclusion that Microsoft is missing the boat around dynamic languages and scripting in general. I have been a huge advocate of strongly typed languages, and not confusing scripting with a real application development platform.

Scripting is great for glue code - the same thing that VB1 and 2 used to be great at. VB3 started to get into the serious app development with rich data integration, and VB4 brought us into the 32-bit era, and in a way back to glue code. VB4's embracing ActiveX controls gave VB developers an entirely new place to play. I remember working on an application using a beta of VB5 and writing my "hard core code" in MFC ActiveX controls. After a while I started writing more and more of the code in VB, because it worked and wasn't the bottle neck in anyway for the application.

I think that scripting and many dynamic languages are in the same camp. They are great for small applications and writing glue code. Look at Google Maps, the real processing is on the server, and the client side AJAX is just the glue between the user, the browser, and the backend server. I would argue that something more beefy like Outlook Web Access (a Microsoft AJAX application, writen before AJAX was the name) demonstrates more of the limitations of writing the majority of your client interface in script.

Regardless of the limitations, our singular focus on strongly typed compiled languages has blinded us to the amazing productivity and approachability of dynamic scripting langauges like Python and Ruby. I'm super excited that we are changing this. Hiring Jim Hugunin is a great start. I hope we continue this, and really look to add a strong dynamic language and scripting story to our developer portfolio.
