I also hadn't heard the term, but after reading this I realised I was a dark matter developer. I've given talks at a couple of conferences, but I've only ever contributed back to open source projects by opening issues and writing a couple patches. I've tried to convince my employer to invest time in contributing back, but I've never made it a priority in my personal life. I wouldn't say that I'm more risk averse than other developers, but I have a healthy does of perfectionism that tends to get in the way of ever releasing anything. On some level I feel like I'll be judged for anything I put in the public eye if it isn't 100% perfect. I recently went to my first meetup though, and everyone there was super friendly, so maybe I'll come into the light. :)
