I am in the interesting position of having a highly successful website that is never read by anyone I know. With the notable exception of one of my cousins, no one in my family has ever cared to look at it, and no one out here in Michigan even knows it exists.
This raises the possibility of writing candidly about people I know with relatively little fear of reprisal. Like a noble who goes about disguised as a mendicant, I can move freely in my circles of society without anyone being aware that my observations of their activities and personalities might one day be read by hundreds of attentive readers.
