She suffered from poor health, which had got a lot worse recently, and she stopped posting in the last couple of years. When I am trying to imagine the point of view of a reasonable conservative I often use Mistral as a mental touchstone. Probably still will.
Among my online friends she was particularly close to kerravonsen, who knew her much better than I did. They spoke fairly often by long distance phone. I know many of us will miss her. I certainly will.
