:I am sorry to hear that you found my edit summaries to be "unhelpful".  Your tone appears (perhaps unintentionally) rather strident.  I am quite aware that I asked no one "on wikipedia"... that is, I believe, the point of a wiki.  I was the only person to "approve" my edits.  Yes, I am also quite aware that the article you refer to (Cadillac DTS) does not "belong" to General Motors.  I have no affiliation with General Motors, and can hardly imagine that they would spend their time "approving" wikipedia articles in any event.  I was attempting, as all wikipedia editors are, to improve the encyclopedia project.  When making somewhat minor copyedits and clarifications, I often use a generic edit summary, such as the one you remarked on.  Thank you for your comments, best wishes on your future productive editing.  —
