Google+ invitations no longer so scarce

From PC World: Apparently Google is feeling more confident about expanding the population of its social network, because the "invite people to Google+" button has been visible for well over a day.

The button had been fleetingly appearing since the Google+ launch on June 28, so Google's decision to leave it up carries the message that the company is less concerned now about a big growth spurt. Of course, the company can still throttle the rate at which it delivers those invitations or the rate it signs up the new members when they open their invitations, but the relative ease I've had inviting folks to the service since Friday indicates to me that Google is loosening up.

Last week, during one moment when it showed the invitation button, Google said it was allowing the Google+ population to double from the first-round beta test.
The once-rare Google invitation button has been available for more than a day.

Google+ invitations initially were extended only to Googlers, the press, some in the nerdy in-crowd, but demand has been high. Those who wanted to invite their friends had to resort to a circuitous and somewhat unreliable e-mail notification technique.

Opening the invitation process is a big step short of letting just anybody sign up on their own, of course. The process keeps growth at a slower pace, makes it less likely that bots and spammers will start polluting the system, and helps avoid the problem that people will show up on the service with nobody in their social circles.
