As much as I like Scala I find that hard to believe. I actually look for Scala in the job listings and I never felt it came up that much, compared to say Python or Javascript. A dumb search on the page for scala mostly turns up scalable ...
This is one reason why we need regexes (to name just one point) in browser and other search. I've said before in other places that Gmail could benefit from an SQL-like query language, for example. So could many other web and non-web apps. Google search too. One potential issue is excessive load on the servers if it gets used a lot, though.
