Well, this is a topic I feel very strongly about, and in some ways there is a bizarre circularity to discussing this on HN for me. I'll try to provide some context. I started out BBSing as a kid in the 80s, usenetting in the 90s, and I felt post '00 that the dominance of the www seemed to be fragmenting and destroying the feeling of specialness that digital communities possessed. Discovering 4chan in 2005 triggered a flash of recognition, a sense of "aha! this is where the creative spirit of Ye Olde Nettes is!" I've always thought the absence of personal ego and freedom of expression of 4chan at its best represents a higher ideal than voting-based communities, and paradoxically enables richer self-expression than the banalities of myspace and facebook. For years I held myself aloof from other online communities, reading them, but always reserving my participation for 4chan. Last year I finally broke down, and my very first contribution to HN discussion was to vent my frustration with the idea of making facebook accounts a prerequisite to the use of other sites!
tl; dr - Long time 4chan user finally compromises his internet ideals to join HN just to complain about sites piggybacking on Facebook. A few months later, moot makes use of his new site dependent on Facebook.
