I've posted about Dynamic Typing a lot recently, but here's a great post I just came across:
From the Walnut guide to the E language
"Many of the most complex yet most reliable systems in the world today have been developed with dynamically typed languages. If you are a Java programmer, unshakeably convinced of the perfect correctness of static typing, all we can do is urge you to try E first and form your conclusions later. We believe you will find the experience both pleasant and productive, as the long heritage of programmers from Scheme to Smalltalk to Perl and Python have found in the past."
There you go - it's nice to have allies.
