Someone out there is using fiduciary! A few weeks ago, I was riled up about word origins and said:
Now sure, no one in their right mind ever needs to mention "fiduciary" on their blog, unless, of course, it is some lawyer thing.
Now, I've run across a PghTech article (not a blog, and not especially lawyerly) that mentions fiduciary. And not only does it mention it, it calls it "legal jujitsu." Rather impressive wordcraft, I must say.
