New and not-popularly adopted languages tend to have more senior people learning and developing software using them; this leads to people (read: recruiters) looking for the people with experience.. People equate the quality of software with something innate with the language, or that the developers are exceptional. Then after being popularly adopted it slumps in perceived elegance and goes on a downward spiral until it ends up like PHP, Ruby or JAVA. (not to undersell the folks who predominantly use those languages, I'm just picking languages that I've seen follow this pattern)
