Facebook, at least for the present, cannot be ignored. It is a sort of virtual “read all about it” billboard for newspapers, a way of drawing attention to a whole range of articles — interviews and features, for example — that never see the light of day on Google News.
Note also that it is a far more powerful tool than Twitter, which has failed to monetise itself and has never turned a profit.
Facebook, even if its growth is tailing off, remains a phenomenon.
