Or have you ever been learning a big stack of modules, like DBIx::Class or Catalyst and stumble from time to time over a new method name and you did not know where to look for it's documentation? I have once even wrote a script that generated an index of all methods documented in some code directory tree. It worked for me when learning DBIx::Class - but you needed to be very careful when choosing what you are indexing - you indexed too much and the list just got too long, you indexed too little and it's coverage was too limited.
Until discovering Pod::POM::Web I did not know that what I need is actually a full text search over all the Pod documents - you cut and paste the unknown method name into the search box press Enter and voila you have list of modules that document that method. And if you know that it comes from one of the DBIx::Class submodules you just add DBIx::Class to the search criteria - and don't get all the Class::DBI documentation pages. No problem with too long index lists. Someone should hack it to run against a full CPAN mirror and beat the other CPAN search websites.
