WWW::Mechanize, CPAN::Mini and Perl::Tidy are far too specialised to be of interest to most people. I've never used Mechanize in my own code and am unlikely ever to, for example. CPAN::Mini is useful only to a small subset of users. And Perl::Tidy likewise. "Perl on Windows" is of course only useful to people working on Windows or who want Windows-specific functionality. Again, a small subset of perl people.

And I agree with the other comment that Moose/POE/Catalyst/Jifty/... are far too big for a brief overview to do them justice. But I'd add that they're also far too complex for beginners even if you dedicate a whole tutorial to each one (POE still confuses *me*, and I still don't see the point of Moose or even know what Jifty *is*). And again, they're only useful for a small number of people.

The most important thing for new perl users is the community, so concentrate on that and the CPAN. There's lots of useful tools based around the CPAN, so show them too. eg, the diff tool on search.cpan.org, cpantesters, etc
