So I was reading a blog by … well, let's just say by A Name In The Business, which said "Site Groups have been depreciated" in MOSS. After a few moments of pondering whether he he was referring to the straight-line or double-declining variety, I realized that what he meant was that "Site Groups have been deprecated" in MOSS. Ok, so the guy made a typo; what's the big deal? A quick Go-Ogle search found 14 misuses of "depreciated" for "deprecated" on the first two result pages, so I believe this is more than just a random mistake.
To depreciate means either to lose value (not the meaning intended here) or to belittle (the opposite of "appreciate"). I don't think anybody is belittling Site Groups (well, I'm not anyway). To deprecate is to disparage or express disapproval; this is what Microsoft is doing to Site Groups.
I realize that it has become common to use "deprecate" when you mean "depreciate" in its belittling sense, but that's the wrong way around. The 14 misuses I found used "depreciate" when they meant "deprecate".
All right, rant over. Back to work … ooo wait, what's that shiny thing over there?
