Good point and that's why I recently came to an interpretation that search engines return some kind of "tables" for us (but not in the tabular form). List of links are rows, and for every link we have properties ("columns"): the title of the page, the date, the snippet with phrases containing our terms. The same is true for stackexchange.com/stackoverflow.com pages, the answers are rows, the text, score, comments are properties of this row. We are used to scanning this "tables" either for finding best answers or exploring multiple variants of answers. But single answer for everything is too limiting.
