In this latest installment, two things stick out to me:Java continues to be the biggest enterprise target yet Java (and every other “major programming language”) is on the wane.You can see a representation of this here: Ruby and other “web languages” are on the upswing, while stodgy old “major programming languages” are on the decline. Still, if you’re selling into the enterprise, the installed base is more comfortable with .Net and Java than the sexy new languages. (I mention this because at a recent gathering of a few open source startups, we were trying to decipher the reasons behind our differing average deal sizes.
