It's "Plack" not "Plank" :)

The benefit is that once your application works with PSGI then you can 
move it between mod_cgi, mod_perl, fastcgi, Starman, Tatsumaki, Twiggy, 
etc. It's not tied to a particular web server since there are Plack 
adapter layers that can be used to make a PSGI application run on any of 
those.

Most web frameworks try to abstract away most of this already, but they 
all do it in different wants. PSGI is meant to standardize all of these 
so there's not so much wheel reinvention.

Also it allows people to write middleware components that can be run for 
any PSGI application. So a catalyst app running under mod_perl can use 
the same debugging toolbar as a CGI::Application app running under Starman.
