New social networking math?
People rushed to sign up for Google's new social networking service, but they're taking their time returning to the site.
That's the read by Experian Hitwise, which released a report saying Google+ drew 1.8 million total visits last week. More than 10 million people registered for the service after it launched in a limited test starting June 28.
"Everyone was clamoring to get the invites, maybe they're not returning back," said Experian Hitwise spokesman Matt Tatham.
