I don't and when I hear it, it always sounds odd..
I think I used to and a big fuss was made in 7th or 8th grade when I pronounced it; the teacher said something about Shakespeare and I wasn't sure if I pronounced it and wasn't supposed to or didn't pronounce and was told that I should. Anyway, don't think I do nowadays, but I suspect the answer is that I usually do not, but sometimes do.
Does anyone pronounce the "t" in soften? Of course not, the t is silent as it is in often. I also treat the "u" in aunt as silent but I think that's more of a regional thing. Speaking of the silent "t" there's a story that Jean Harlow met Margot Asquith and pronounced her name as "Mar-gott". Lady Asquith told her the "t" was silent, like the "t" in "Harlow"
