Good points on the virtual gaming impact on the economy, and more importantly a valid conclusion from a financial analyst:
But according to Owyang, both services have their work cut out for them. Google+ is off to a good start, but he doesn’t think a compelling reason exists yet for mainstream users to switch over from Facebook. That’s why the company announced it was going after casual games, to attract new users. Meanwhile, Facebook needs to be less reactive to Google+’s announcements and become more aggressive, he says.
It was inevitable for Google+ to start having games included with the service, but the reason is to make the service “sticky”, not to attract a larger user base.
