I only can chime in humbly and say, that I, too, feel a great loss.
Her tone certainly set standards here at MR.
I have downloaded and read quite a number of books provided by her. At times, when looking for new books, I just filtered by her name, as the literature, provided through her often met my taste.
Never having met her or discussed with her (even on this quite abstract digital basis) I still feel, I would have liked her a lot.
My condolescences to her partner and family.
