Self-promotion with virtually zero content.
Not because we are lazy and don't read (I mean that does happen too, and I'm as guilty as anyone, but not just that), but because we all have itches that need scratching and all it takes is for someone to bring up a topic and we unload that pent up energy.
DevEx I think in some ways tries to address issues of empathy and that's a phrase I've been waiting for someone to coin (combination of saying it and enough people hearing it, the former I can do, the latter not so much) since about 10 years ago.
