Meme alert! Another person has been hitting the conference podium to talk about that ... special glow you get from cooperative coding. It's that glow of oxytocin.
Debbie Moynihan recapped a talk by Tor Norretranders at EuroOSCON last September.
Norretranders is a Danish writer and thinker. According to Moynihan, he told the conference that people participate in open-source projects to "glow, show, flow and 2.0."
Actually, it looks to me like Norretranders is the originator of this concept. It evidently resonated with Rasmus Lerdorf, the originator of the PHP programming language; he's been mentioning it in his own talks.
