A while ago someone made fun of me for saying “PIN number”, since the “N” already stands for number. Since then I’ve been careful to use all those ubiquitous TLAs properly. But I’d been dutifully calling Java Server Pages “JSPs”, only to find that all the documentation says “JSP pages”, which seems redundant. I guess it’s OK because “JSP” is the designator for the type of the page (like HTML page, which just happens to not have the word page in it). I dunno. I probably shouldn’t worry about proper usage when all of us are making it up as we go along.
