Happy talk must die

Happy talk is fluff and often self-congratulatory promotional talk, usually intended to be friendly but generally just getting in the way of people trying to get a job done.
On the web, and to be honest, in most places, happy talk must die.
Brenda Ueland, in her book If you Want to Write , put it perhaps the best I have seen:
'Oh, this over-explaining! It is the secret of all boredom. It is like this: You, the writer, go slowly and laboriously with many words, while the reader gropes through it, saying impatiently: “Yes, yes, hurry, hurry up! I see it—I get it! Go on to the next."'
Happy Talk Must Die is a gem from Steve Krug's legendary book on usability, Don't Make Me Think . Here's an excerpt on Happy Talk .
Also from Don't make me think: Omit needless words
