python simply not scaleable enough for google?

That time is now, in many cases.

I still stand by my strategy published in Unix World
ages ago: get it working in Python, profile it, optimize
it, if you need to do it faster code the inner loops in
C.

Of course on google app engine, the last step is not possible,
but I don't think it is needed for 90% of applications
or more.

My own favorite app on google app engine/appspot is

    http://listtree.appspot.com/

    implemented using whiff
       http://whiff.sourceforge.net
    as described in this tutorial
       http://aaron.oirt.rutgers.edu/myapp/docs/W1100_2300.GAEDeploy

not as fast as I would like sporadically.  But that's
certainly not Python's problem because the same application
running on my laptop is *much* faster.

By the way: the GO language smells like Rob Pike,
and I certainly hope it is more successful than
Limbo was.  Of course, if Google decides to really
push it then it's gonna be successful regardless
of all other considerations, just like Sun
did to Java...
