Posting or commenting imposes a cost in the form of a claim on the attention of your readers. It also provides a benefit in the form of information.
Perhaps the burden on writers should simply be to justify that their writing is relevant enough, and likely enough to be correct, to justify making this claim on readers’ time and attention. This burden should be higher on shared fora than personal blogs, higher on posts than comments, higher for parent comments than replies, higher for off-topic than on-topic posts, higher for speculation than for fact posts.
