I don't really follow Racket, but I recall that few years ago one apparently fairly significant contributor within their community wrote a blog post about Racket having a Missing Stair problem involving another even more significant (possibly foundational) contributor.

I'm a complete outsider, cannot find that blog post any more, and also just not invested in the language at all, so I'm hesitant draw conclusions about the validity of any of the accusations that were thrown back and forth at the time, but it seems pretty obvious to me that it's inevitable that the community will end up being split after an event like that.

if it's Felleisen, then i'm surprised. i've met him on a conference for a couple of days about a decade ago, and my memory is of a nononsense guy with whom our vision of programming resonated a lot.

i was coming from the CL side of the isle, i hadn't known his work prior to that.
