AFAIK one of the objectives of Stack Overflow is to make sure anyone can come here and find good answers to her Perl related questions. Certainly beginners would ask what is the best online source to learn Perl but others might just want to ask a question.
Probably the friendliest place is the Monastery of Perl Monks. It is a web site with a rating system similar to but more simple than Stack Overflow. You can find lots of good answers there and if you don’t find an answer you can always ask.
The other big resource would be the mailing list of your local Perl Mongers group.
Where do you go when you are looking for an answer to a Perl related question?
It’s worth noting that http://perlmonks.org, in addition to the fora, has the Chatterbox, where simple questions can be answered immediately in conversation with other users.
It requires setting up an account and logging in before using the Chatterbox, though.
