Then maybe CPAN's advantages shouldn't be explained as "gem install", err... "perl -e -MCPAN "install net::foo". Explain the _actual_ strengths of CPAN that make it a killer app.

Oh, and "It has MOAR!" isn't really a good argument. I've authored two gems, I think. Those are the only two times in two years of using Ruby that I haven't had the ability to just install the library that I needed.

(I loved Perl for years until I found Ruby, then never turned back...)

Tests. Integrated Bug Tracking. There's 2 reasons.

Sweet! Then lead with that. I'm not saying that CPAN isn't better than Rubygems somehow, but that "easy installation" isn't a selling point.

try "cpan Module::Name", which installs the requested module

Sweet. That's still on par with Rubygems, cabal, and everything else, though. That wasn't my main point.
