Hmm, this has been true for some projects I worked on. When there is a stable dev lead for many many years. He needs to teach others his approach. Then it's perfect. People tend to keep things that work well. Just don't hire those who want changes:)
This doesn't need to be confirmed: LiveScript was renamed JavaScript back in 1995 so it would be percepted as hot.
On a more universal level, it shows just how ridiculous most buzzwords are. As we laugh today about JavaScript and the Java Ring, we will laugh tomorrow about today's ubiquity of the "cloud."
