I started my freelancing career with XSLT (XML transformations) and got a Google Summer of Code stipend 2011 and a job offer right after that. Riding this train since 2011. Although I'm doing XSLT very seldom nowadays it got me my foot in the doorstep, guessing with a common programming language and not going niche I would have never made it (thinking that Asian and Russian programmers are much better in broad known languages than me).
