What? It's a serious question. It'd be great if a flagship GNU project was a serious competitor with other programming languages, but it honestly looks like Guile is being kept afloat by one or two people. Why is mentioning this trolling?
Sorry, but it seemed like you were trolling. Guile is not a one man show. I have been active in the Guile community for 5 years now, so I know. I will admit that the bus factor in the compiler portion of the code is high, driven almost exclusively by Andy, but he has done a significant amount of writing about how the compiler works and even listed several other improvements that can be done in an effort to get more people involved. I have no experience with compiler hacking and yet I was able to implement an optimization and get it into the 2.2 release. The commit history alone isn't enough to understand the group of people that push Guile forward.
By "shame you're being downvoted", do you mean you agree that I'm trolling? Care to explain why? davexunit's contributions have nothing to do with this.
