Ruby's on a good part of its development. See, we're at the point where you don't need to write your own CGI, XML, or database library to use it. But there's plenty of libraries that are at the 0.6 point that need somebody to push them to 1.0.
As far as breathless fan pieces go, this isn't too bad, though I have trouble reading reason #9 as anything more than "If you want to do anything slightly less than ubiquitous, you have a terrific opportunity to start or join a tangential project to get your job done."
I'm not sure the lack of the CPAN is really an advantage.
