Allan,
I sympathize with the printers, word processors, etc.--as well as with news anchors who are given badly written copy to read. Ideally, there would be two-way communication, so that errors can be corrected. When time prevents this, there is a real problem.
Maybe the problem is that no one knows whose responsibility it is to edit the document.
When I was doing my doctoral dissertation, there was a key, word-- "predication" (or "predicating," "predicated")--which recurred throughout the document. My typist took it upon herself to change every instance to "prediction" (or the comparable form of that verb), without asking me. She had to do the document over (back in the dark ages when people still used typewriters and white-out) and resented my not wanting to pay extra for that.
I also frequently find that my real name (which can be spelled several ways) gets "corrected" in the records of credit card companies, utilities, banks, etc., after it has been spelled correctly for years!

As I said above, I think the deterioration of language reflects our society's failure to value correct language usage. In an age when we Americans brag about "excellence," we don't require anything close to it for getting a job writing news copy for major networks, ad agencies, newspapers, etc!

A tangential rant: "We want to warn you, these pictures are graphic..."
What else could pictures be?

Back, sort of, to the original topic of the thread. I know it is considered correct to make a possessive of a name ending in "s,""sh," or "z," by just adding an apostrophe--e.g., "Chris' Steak House." But in spoken language it sounds really weird to me ("President Bush' speech ...", for example). More importantly, it seems quite silly and unnecessary. Our language is full of words like "Mrs.," "kisses," "consensus," "bushes," "hisses," etc. Why, then, should it be hard to pronounce "Joneses," or "Jones's, "Bliss's," "Chris's," etc?
