Dorothea Salo, writing in Caveat Lector (http://cavlec.yarinareth.net/):

Some people speak about themselves and their families in clichés and polite fictions for many of the same reasons corporations speak in empty, sonorous PR, not least among them desperate fear of the truth. Some people, submerged in the family fictions, lose their real voices in part or wholly. Blogging threatens such families for the same reasons it threatens PR-dependent corporations. It threatens the fiction, the public façade of perfection, the private walls around anger and pain and disagreement and error. The “public” nature of blogging is only an excuse, really, for those who want the façades maintained. Public or private is not the issue; the issue is talking truthfully, or writing truthfully, at all. To anyone.
