Adland, like much of the business world, appears to have gone mad for Facebook (Live Issue, page 12). It's tempting to view the collective hours spent logging on looking for "friend requests" as a waste of time, but you'd be wrong. Any self-respecting employee of the media world should have at least one serious online obsession. Facebook is giving a slightly older generation a taste for digital leisure, helping it to understand what younger consumers are up to. It's also a pretty handy networking tool, something that adland's hungrier practitioners have taken on board.
