I adore Catalyst. It has caveats (deployment requires a persistent environment -- cf, modperl or fastcgi -- to be reasonably fast) and it has a somewhat steep learning curve. But the docs are always improving, the code base gets wider and smarter all the time, there are more and more articles and examples online, the community is great, and many other Monks are Cat users/devs too so you can ask questions here as well as on the Cat list. Search in here for Catalyst and you'll find related stuff including possible reasons to use other things like CGI::Application.
