Did you catch j3w3l’s post on the events of the weekend over at Healing the Masses? It’s a tour de force and well worth the time. The comment section is worth a read too, as every typical trope that could get called out on the subject matter plays out with a smart group of commenters that shoot those tropes down as quickly as they pop up.
Quick edit: For additional really great writing on this subject also check out Arthur Chu’s advice to geeks and also Laurie Penny’s call out of what these kinds of activities really are. There’s no better writing on the subject across the internet.
