FYI - Just want to make sure that everyone is aware that there are two lists:
suby-ruby
This is the one dedicated to suggestions for Ruby and RCRs
https://lists.berlios.de/mailman/listinfo/suby-ruby
suby-muse
This is for general programming language speak.
Not necessarily anything to do with Ruby.
https://lists.berlios.de/mailman/listinfo/suby-muse
Recommend subscribing to both unless you're specifically not interested in the
Ruby list ( but how could that be? 
Both are low traffic.
Enjoy!
