My best guess is that the usual ratio of “time it takes to write a critical comment” to “time it takes to respond to it to a level that will broadly be accepted well” is about 5x. This isn’t in itself a problem in an environment with lots of mutual trust and trade, but in an adversarial context it means that it’s easily possible to run a DDOS attack on basically any author whose contributions you do not like by just asking lots of questions, insinuating holes or potential missing considerations, and demanding a response, approximately independently of the quality of their writing.
Not strictly related to this post, but I’m glad you know this and it makes me more confident in the future health of Lesswrong as a discussion place.
