“and” or “but” followed by a comma
In recent years I’ve noticed an increasing use of “and” or “but” followed by a comma, as in this example I saw today in an email: “We don’t believe these updates change our practices but, we want to communicate this information directly to you.” The rationale seems to be that a pause is intended after the conjunction, but clearly this violates the traditional rule about punctuating a compound sentence (as per this sentence).
In today’s Providence Journal the lead editorial, ”Tough but vague Romney,” includes this: “Mr. Romney has demanded that Iran stop its program aimed at making nuclear weapons and suggested the [sic] Mr. Obama hasn’t been firm enough. But, the former governor hasn’t said how he would do that other than, perhaps, give more support to the Israelis to attack Iran.”
I realize the paper’s evident lack of sufficient proofreading might cloud the issue here, but [not "here but,"] I assure you this is not uncommon in today’s newspaper and other published writing.
So does this bother anyone else besides me?
