I'd consider myself to be one of these developers. I don't blog, I don't Tweet, and my public GH contributions are sparse at best. I'm a fairly senior engineer in a large company. What bothers me about this post is the idea that I must be lagging behind on using the newest technologies just because I don't Tweet about it?
Conferences, in my experience, are mostly a waste of time. I can usually watch the keynotes online after the fact if I care to. I'm not interested in joining discussion groups and posting; like the vast majority of people, I'm content to lurk, but I'm not blind!
So yeah, I'd be very comfortable challenging a light-visible developer on pushing/using new technology and generally being aware of the landscape. I just don't care to talk about it constantly.
