… as I predicted in the post Waiting for Facebook’s Other Shoe To Drop: Advertising, BusinessWeek writes:

The company has developed a potentially powerful kind of advertising that’s more personal—more “social,” in Facebook’s parlance—than anything that’s come before.

Personally I don’t like commercial entities to use my friends to advertise to me … but I guess it’ll be unavoidable.

By 2020, and likely much earlier than that, the ads will also take my location and my friends’ location into account, and the history of our locations over the past 10 years, and how long we stayed where, and what we actually bought (not just what we said we liked), and possibly a lot more… Clearly something that will raise GDP. But possibly also increase impulse buys and reduce the savings rate.
