Avi Bryant, creator of Seaside, brings down, what I tried to say in Written in Ruby. Only a Ruby implementation in Ruby will enable significant speed improvements and allow a future development with the current momentum.
Therefore go ahead and help the people with Rubinius.
Remark: Christian Neukirchen added another aspect … somehow … but I think, this is still another level.
The Ruby Ahead is my private blog. It once covered
the development of my Master's thesis and the occompanying code.
