I blog for work. I don't discuss it with family. I think I'd find it very stressful answering the "why did you say that" questions.
The corollary of this, is that I write notes by hand in almost every meeting I attend, and never ever read them again -But for things like IETF I do a mixture of .org and meetecho (markdown) because there is at least some possibility others may get value from the shared log in meetecho, and I know I will use the .org to .. write the blog.
