i think that creating of maillist named ruby-chat or ruby.beyond is
not the best way to separate traffic. noone thinks that his interests
is "beyond" of ruby or he just chatting and stole time of another
subscribers

my personal interests is
1) improvement of language by implementing common usage patterns in
ruby itself
2) changes to language desirable to work on large projects
3) language design principles - area where i and Pixel (and Matz?) can
answer to your questions

as interest to ruby grows, this maillist grows too. may be it's time
to send ruby progress group to separate maillist
