An interesting talk on to the future of the (Social) Web by Forrester's CEO George Colony during LEWEB 2011.
He foresees three major "Social Thunderstorms" : The Death of the Web (not the death of the Internet), The Social saturation, and the Social Enterprise. Of course next to these trends attention needs to be paid to the real social thunderstorms namely the Social Effects of the Social Media 2.0 era. Hope to have more to say about this soon.
