Looking through my email now it looks like most of the lists I'm subscribed to are through meetups on meetup.com. I'm a member of a number of meetups that are related to technology I use (e.g. Ruby, Javascript), or topics I'm interested in (e.g. data journalism, I'm a member of Hacks & Hackers). I receive either the emails in real time or as a daily digest. I have only turned to those lists once looking for work and it was a big success.
