I have an account on use.perl.org that is configured to send me email updates of new stories posted.

I used to be subscribed to all the Perl 6 mailing lists, but after a while I noticed that I wasn't able to read more than 5% of the traffic. I unsubscribed from them and now I content myself with pdcawley's most excellent summaries. I also read Rafael's summaries of p5p, to keep an eye on what is happening in current Perl. Both of these resources can be found on use.perl

Mark-Jason Dominus runs an entertaining project called Quiz of the Week, where Perl puzzles are posted, solved and discussed, and is well worth the visit.

I founded a Monger group that will celebrate its fourth anniversary next month. We meet every second Wednesday, for food, drinks and discussion. Sometimes we even talk about Perl.

Many modules and projects also run their own mailing lists. For instance, I am subscribed to the Sybperl list, run by mpeppler, that discusses Perl and Sybase.
