I can’t imagine life without the Public Media Group on Facebook. OK, maybe that’s a bit of an overstatement — but I certainly couldn’t do my job half as well without it. I was talking about it with a colleague last week, and he mentioned a listserv for data visualization geeks that he finds similarly invaluable. Resources like these enable a kind of ongoing, informal collaboration and run like an unsung power supply throughout the field of journalism. In the Facebook group I mentioned, people debate editorial ethics, offer technical solutions and discuss industry news. Where do you turn for this kind of collaboration? Vote in our poll below for general answers, and get specific in the comments below. We’ll be putting together a resource with the best groups in a future post on Collaboration Central.
