I was just about to comment that I disagreed with Mr. Richards' objection to the word "CD's," noting that I thought that was the proper plural form for abbreviations (like 1960's or A's) when I noticed that the pop-up ad that appeared when I opened the link to the NYT was advertising "CDs, DVDs and CD-ROMs." Now I don't assume some blathering copy on the Internet to be the arbiter, but what do you all think about "CD's"?
