From the late 80s through the early 2000s Lisp was my language of choice. The post author went through many of its advantages -- mostly true. I even went so far as to write an entire compiler and environment (a several man-year endeavor) to design two different runtime oriented dialects called GOOL and GOAL used in 8 Naughty Dog Crash Bandicoot and Jak & Daxter games. All 30-60 FPS action games -- 40 million copies sold. All written in Lisp! (more or less)

Eventually, it was Ruby that got me off Lisp. It does most of what made Lisp great, and the support factor is huge. There are clean standard libraries for everything, the garbage collector is good (the one in ACL is was so awful and dated -- I last used it in '07 -- you pretty much had to turn it off.

I miss the S expressions and the macros. But you can do most macro like things with a good block expression in Ruby, and you can even do auto-generated macro like functions with strings. It just isn't as elegant as Lisp.

The Ruby class system is a bit baroque, but it's actually better in many ways than CLOS, which suffers from being too dated. In Ruby you can do a lot of very cool things with extend and include. It's just a slightly different way of thinking.

The implementation isn't the fastest, but it's good. The Lisp implementations were all clunky and felt like 80s codebases. Oh wait, they are.

Support. The rate of change in Ruby is 1000x that of Lisp. Some new website has an API -- someone writes a Gem immediately. In Lisp you don't even have a really standard networking library!
