I started to write Sleep when I was an undergraduate around 2002. My goal was to develop a Perl-inspired language for the JVM with an API to embed it into applications. Sleep predates a lot of JVM languages. http://sleep.dashnine.org/ http://sleep.dashnine.org/ It's not mainstream but I used it in After the Deadline, jIRCii, and now Armitage. When jIRCii was more active I had several scripters using it to contribute to the client. Scripts ranged from a few lines to several thousand lines of code. I receive emails occasionally from users but there are not too many Sleep hackers out there. Still, I'm doing better than most languages since my number is greater than 1. :) So my advice for would-be language hackers: go for it. Writing Sleep was one of the greatest learning experiences for me as a programmer. I now look at languages through an entirely different lense. I don't get too excited about fads or syntactic sugar as I know how I'd implement them. Also, it's not that hard.
