Good points Sassy. Though my understanding is that Dooce does sanitize and fictionalize in a way that works for her and protects her daughter.
I know that Dooce knows the risks of blogging family, given her long track record and real-world pushback from family, friends, and random internet jerks.
I think I fall somewhere in the middle between your point of view and Dooce. Everyone finds their own level of comfort and intimacy with their audience, along with candor and details about family/friends.
