People turn to software

People turn to software to learn the meaning of words, learn which countries were bombed today, and learn to cook a paella. They decide which music to play, which photos to print, and what to do tonight, tomorrow, and Tuesday at 2:00. They keep track of a dozen simultaneous conversations in private correspondence, and maybe hundreds in public arenas. They browse for a book for Mom, a coat for Dad, and a car for Junior. They look for an apartment to live in, and a bed for that apartment, and perhaps a companion for the bed. They ask when the movie is playing, and how to drive to the theater, and where to eat before the movie, and where to get cash before they eat. They ask for numbers, from simple sums to financial projections. They ask about money, from stock quote histories to bank account balances. They ask why their car isn’t working and how to fix it, why their child is sick and how to fix her. They no longer sit on the porch speculating about the weather—they ask software.

Even consider reading email. Most current designs revolve around the manipulation of individual messages—reading them one-by-one, searching them, sorting them, filing them, deleting them. But the purpose of reading email has nothing to do with the messages themselves. I read email to keep a complex set of mental understandings up-to-date—the statuses of personal conversations, of projects at work, of invitations and appointments and business transactions and packages in the mail. That this information happens to be parceled out in timestamped chunks of text is an implementation detail of the communication process. It is not necessarily a good way to present the information to a learner.

Similar arguments can be made for most software. Ignore the structure of current designs, and ask only, “Why is a person using this?” Abstracted, the answer almost always is, “To learn.”

Case studies

The author also offers excellent case studies of how to represent data so it's more useful for the users.
