I logged into my Google Voice account today to discover I can now invite others to the service. As up until this time Google was controlling the invites as it scaled up its Voice infrastructure, allowing users to send invites is a positive sign that the system is handling growth well.
In the roughly four months I’ve been using the service, Google has made many enhancements to the service, from the user interface to its ability to collect calls to more numbers. AJAX improvements to the user interface support one-click marking of messages as read, a drop-down menu on messages to provide additional options, and a tabbed settings pane. I no longer encounter busy signals when calling numbers in certain regions, nor do text messages fail to reach their destination. At the same time, Google has released a BlackBerry application, added support for the service to phones running its Android platform, and attempted to release an iPhone app as well. Add to that users’ ability to send invites and it would seem the beta is progressing well.
