Google has made the social networking site Google+ open to the general public. The site was operating in an invite-only status for its first three months.

Additionally the company has introduced a video “hangouts” feature where up to10 people can chat simultaneously. The feature will be available to all Android smartphones with front-facing cameras, with iOS support coming soon.

This comes two days before Facebook’s annual f8 developer conference, clearly on purpose. It is expected that Facebook will announce integration with music services and there will be more real-time updates of what friends are doing.

Google+ racked up over 25 million members since launching in June 2011 and is expected to reach 100 million members by the end of the year. Facebook, by contrast, has around 750 million active users.
