I’ve been writing for as long as I can remember and still find writing letters that begin “To whom it may concern” very tedious. It’s not very engaging wordplay. It’s boring. It’s a business-world casualty hit to the writing voice. But there it is, because formula is sometimes important.
However, this is the emerging world of new media. Rules are changing. So If I get a vote, I vote that one’s the first to go.
