Perl still has its uses. For tiny projects (100 lines or fewer) that involve a lot of text pattern matching, I am still more likely to tinker up a Perl-regexp-based solution than to reach for Python. For good recent examples of such things, see the timeseries and growthplot scripts in the fetchmail distribution. Actually, these are much like the things Perl did in its original role as a sort of combination awk/sed/grep/sh, before it had functions and direct access to the operating system API. For anything larger or more complex, I have come to prefer the subtle virtues of Python—and I think you will, too.
If you search for the main idea of the piece (an actual quote that states the main idea) you only find it finally in the last paragraph; “The fatal misconception behind brainstorming is that there is a particular script we should all follow in group interactions.” If you drop the over the top word ‘fatal’, you have the author’s main idea; that there is no particular script to follow in group interactions. The author actually does support that idea with evidence, evidence which you may argue with, but with enough evidence that he actually does have a point (however flawed and assumption-filled).
