The fact that you go mostly "unseen" online seems completely orthogonal to whether you love programming and keep up with the latest technologies, etc. I would consider myself "dark matter" in the respect that no one knows who I am and I'm not constantly blogging or tweeting about stuff. That doesn't mean I'm not interested in, passionate about and highly competent in technology. I find it kind of insulting actually that someone would assume that just because I'm not loud about it means anything else about how much I care about it or how good at it I am. I'm not totally surprised by this though; for most people, if you're not jumping up and down telling them about how awesome you are they have no way of knowing. I see this a lot in my current job; all the developers know which of their colleagues are kick-ass at their jobs, but you have to sell yourself and your accomplishments to everyone else.<p>TL;DR, I know this is an old article, but it seems there's still some perception that us dark matter folks are all just passionless drones in it for the paycheck, and while there's surely some percentage of us for which that's true, I think it's completely wrong-headed to assume that's how we all are.
