This is waaaay down on the list of things that are important, but using correct terminology is never a bad thing. To not do so just shows that we are ignorant of our own subject matter.
As long as it's done in a spirit of education and not malice or ridicule, I don't have a problem with it at all, even if it happens every day. I would like to think that we have new readers every day, and if one or two people learn something new each time a reminder like this is posted, then it's well worth the time and effort to do so.
And that's just MHO!
