What I found most striking about this article was how different the industry it is talking about seems to be from the one I've been working in. In their industry, Java, .Net and ASP are "new", everything else is "legacy", and Perl and Coldfusion are (admittedly minor) players, but Ruby, Python, and Javascript don't seem to exist, let alone "new" things like Scala, Clojure, and Go.

I'd be interested in knowing how representative the "30,000 websites" they surveyed are of the web as a whole.
