I’m going to try an experiment here.
If you have something to say about the content of a post or have something that extends its points, by all means comment at that post. I’ll generally be lenient about whether a comment is really on-topic, but if it’s obviously not, I retain the perogative to nuke it without notification.
If your comment doesn’t relate to any post, please post it here. But do NOT (repeat, NOT) post full articles as “comments.” For copyright- and readability-related reasons, limit excerpts to usually up to six but occasionally up to nine paragraphs. Any comment violating this guideline will get nuked before it appears without notification (unless I have time and feel extraordinarily polite).
As usual, I retain the discretion to allow comments to get posted or prevent them from being posted, and my allowing a comment to be posted doesn’s mean I agree with or endorse it.
