Too often I've seen excerpts that are the content equivalent of a movie trailer for a bad movie-- all the interesting bits are provided in the excerpt/trailer and the remainder of the article/movie is boring fluff and not worth my time. In these cases (where the excerpt has lured me into expecting more quality material), I feel I've been the victim of bait-and-switch just to sell more ads or popcorn.
