This project blew me away. I always thought Scheme was just interpreters and toy programs. Hope this succeeds in making scheme popular. Scheme and Lisps in general way too underrated.
Each scheme is actually much better than people realize at what it's targeted for.
Recently I have to give huge props to Guile + Andy Wingo for guile-fibers. It's proper concurrency, using delimited continuations in scheme. Just frickin' fantastic!
Stock Scheme does not have much in the way of interfaces to the outside world (long story) but there are several Scheme variants where people are doing larger projects. Racket is sort of a Scheme variant, and it seems to be the most popular, but Chicken and Guile are also pretty popular (as far as Scheme variants go) for real-world use cases.
