SAN FRANCISCO gave itself over to ‘Dreamforce’ for a few days in September. Now in its 12th year the event was bigger than ever. Usually busy roads were closed to traffic and rolled over with fake grass, inflatable arm chairs, stages, huge screens and food and drink stops. A 1,000 berth cruiseliner moored near Fisherman’s Wharf to provide extra accommodation. Airbnb apartments were available for $1,000 a night. Stevie, Wonder, the Foo Fighters and Japanese artist Yoshiki played. But this was not a music festival – it was a software conference.
