I've decided to restore comments.
As before, spam, pr0n, threats, commercial advertising, completely off-topic comments, batshit insanity (that means you, David Mabus) and outright lies about matters of fact (yes, you, Rob Singleton) will not be published. Otherwise, I'll publish most everything else. I don't care about profanity. Feel free to call me a fucktard. You don't need a "hard" identity (Google account, email address, etc.); you may use a handle. Word verification is on to keep spambots from making too much extra work for me.
I will rarely respond directly to comments. I will usually respond only to provide additional evidence or in rare cases clarification of points I myself consider unclear. I might create another post generally based on questions or criticism in comments, but don't hold your breath. Usually I've said what I have to say; 90% of criticism is from those who apparently cannot read and understand simple declarative sentences in the English language; it's usually a waste of time repeating my arguments. If you want a specific response, or you want to debate or argue with me in any sense, you can email me. I won't promise anything, but you at least have a shot.
When commenting, you must address me, not other commenters, in a similar fashion as addressing the Chair in parliamentary procedure. If you want to address another commenter directly, do it by email, their blog or your own, or find a message board. In general, I'm not interested in hosting debates between commenters. If I feel a debate is brewing, I may close comments for the post.
I cannot edit comments, and would not if I could. I myself cannot (and would not if I could) keep any records regarding the origin of comments or the locations, IP address and any other identifying information about commenters. I cannot speak for Google.
Occasionally I moderate comments. I do so only when I am being overwhelmed with spam or when a hostile or abusive commenter is harassing me. If moderation is turned on, be patient; I will approve most comments as soon as I can.
Pick a handle or moniker for your comment. With few exceptions, I will not respond or reply to purely anonymous comments. I may delete anonymous comments. If I have comment moderation turned on, I am far more likely to reject a comment if it is anonymous.
I keep a copy of all comments; if you want the text of a comment I have rejected or deleted, feel free to email me and I'll send it to you.
Finally, I retain the unconditional privilege of publishing, rejecting, or deleting comments at my arbitrary discretion.
