Readers may have noticed that I have left the Comments "off" on recent posts. I enjoy readers' comments, and have learned much from them. On the other hand, I find that comments add to my "costs" for each post--I spend time reading the comments, monitoring them for at least token compliance with VC posting guidelines, and responding to them. I find that this extra time commitment dissuades me from posting to begin with. So, while I will sometimes turn comments on, I'll probably leave them off most of the time. I know that this will frustrate some of you who have interesting things to say (or, for that matter, who just want to vent), so apologies in advance.
