An alternative way of measuring programming language popularity and a half-formed thought about half-formed thoughts

I note that BitTorrent is reported to be responsible for 35% of internet traffic. By that way of measuring things, Python has sure grown in popularity over the last couple of years.

There is a lot of "dark Python" in the Universe. Stuff that users cannot see but it is there all the same. The Google spiders, all those Zope/Plone websites, all those happy Microsoft Outlook users with their spambayes plug-ins.

Somebody recently said that dynamic languages provided a way to execute half formed thoughts. Lets hear it for all the half-formed thoughts out there! I wonder what pecentatge of software that meets its engineering goals of being on time, on budget, team friendly, grokkable, as flexible as it is powerful etc. etc. are based on half formed thoughts?
