I wrote an IRC bot[1] to get a feel for Scheme in general earlier this year. I chose Chicken for it, which got me to look into Cheney on the MTA and other implementation details which were really interesting.
The FFI is really nice, given that Chicken compiles to C.
The Chicken IRC channel was a lot of help early on.
The chicken IRC channel is IMHO one of the kindest and most helpful places on the internet.
I have asked so many stupid questions and they were so helpful. I would go as far as to say that they were an important part of me becoming proficient in scheme. The chicken community is my prime example of welcoming and nice open source communities.
I still use chicken from time to time, but I switched to guile for a project with an embedded scheme. I wrote quite a lot of scheme code and suddenly had a prelude in guile that wasn't so easily ported.
I actually came across this the other day. I recently got into using IRC and wanted to learn lisp, so I decided to make an IRC bot. I wanted to get an idea of how this would work in Chicken Scheme (since the documentation for the irc egg was not great) and the only one I could find was your kylling.scm bot. So thank you for putting the code for kylling.scm out there because it helped me get started with the IRC bots I am maintaining now.

All in all an enjoyable experience!
