Keep refreshing it, it works about half the time. I would guess that the new files haven't been distributed to all of their servers yet.

Download the SDK here: http://code.google.com/p/googleappengine/downloads/list

Great news! I'll start playing with it right away.

I won't drop Python for my day to day coding, but having Go as an option is good to see what cool toys we can build.

Any advantage (performance? memory use?) for using Go vs. Python? Or is just programming language preference?

I've been enjoying using Go as a C replacement when I need more performance than Python, but don't actually need to use C. It's been fine for that purpose. I would note that they do keep changing the syntax on a fairly regular basis, the libraries are still young, and I do find the language oddly unexpressive in places compared to even C++ with boost. (E.g., no ternary operator, no list comprehensions, using the same word for all loop variants, and so on.) That said, if you're using it as a C replacement, rather than a Python replacement, I think those are fine trade-offs.

My general feeling is that Go is kind of like a lighter Java. Go is compiled, but also optimized for fast compile times, and it should be faster than python. However, from wikipedia: "Of features found in C++ or Java, Go does not include type inheritance, generic programming, assertions, method overloading, or pointer arithmetic."

Ken Thompson is a co-creator, and the language came from Google. I think Google is just showing that they stand behind their language, and it does seem to hit a sweet spot for a lot of web apps. Although, I don't know too many web apps that need better performance than python.

Faster than Python, better memory use for many types of programs. Compared to Java, less memory use and (I assume) much less start-up time, since no VM is needed. Also, since you can use goroutines, it would seem like you'd be able to do concurrent requests without having to have a special async API like Java/Python have. Go seems like it'll be a pretty great fit for App Engine.
