I "run" the local Perl Mongers. All that really means it that I'm responsible for sending out the "okay, remember: we're going to McGrady's next week!" email.
I'd like to find more local programmers and get them to come hang out. I'm not a Perl fascist. I'd be happy to have Python or .NET or Lisp or C or ALGOL hackers come enjoy a burger and have fun. I thought I'd see if there were other groups, but no dice. I googled for "programmer user group" and "programmer group" and "programmer social group" in my area, but no dice. I didn't even find ABE.pm.
What do I want to search for, and what do I want to do to make ABE.pm more findable by locals who really want to talk shop?
Check out the local Linux groups, or whatever may be around.
There might also be online calendars for tech events in your area. List your events with all of the other events.
Make cards to post on community bulletin boards, etc.
Write an evil manifesto that mentions ABE.pm and get it read on the nightly news somehow.
Slashdot yourself.
I note that the Sydney Python group spams my Linux User Group, but not Sydney.pm
