sri covered a lot. For me,
1, 2, 4, 7 and 8
have been the most helpful.

Comments:

1. on using attributes for handler-to-uri mapping: This is one of the most
clever things I've ever seen done in perl, and it makes me wish I knew more
about attributes so that I could apply it elsewhere in my own work.

2. on engine independence: At work, I'm the one who usually sets up the more
junior programmers (because a lot of them are new to Unix and it would take
them a long time to set up Apache by themselves). With that said, allowing
them to run a site using the built-in server has been a god-send. Also, our
technical director wants to transition to Apache2, and it feels good knowing
that we won't have to recode anything that was done with Catalyst.

4. on the CPAN-friendly directory structure: I'm a big fan of the
CPAN-styled layout, and I'm happy that I can make a distribution out of a
whole site. It certainly makes deployment easier.

7. on the developer-friendly features: The built-in test server, verbose
error_log, and debug screen are all quite helpful. Sometimes, I wish the
output were a bit less verbose, but that's not a big deal.

8. on the use of advanced programming techniques: I've always been a fan of
sophisticated programming. To me, being able to write clean, concise, and
powerful code is a reward in itself.
