During my earlier stay as moderator, I had a pretty quick trigger on comments that were clearly just devolving into sniping attacks.
That will continue. I don't require explanations or apologies or anything of the kind. If I zap something you said, it's either because it violated blog rules, or it was embedded in a longer comment thread that contained an offending remark.
Especially important to remember is not to go after community members. That does drive readers away from the page, and it's not acceptable. (Darla, you know better.)
Most reasonable readers of this page know what's acceptable and what's not.
I will endeavor to let the page breathe, but I won't let it devolve.
