Google has announced that it has opened up Google+ sign-ups to all, bringing the service out of its invite-only shell.
Not only has it made the service available to everybody, it has also announced it is bringing one of its more impressive features to mobile phones – Hangouts.
Hangouts is the group chat service which is direct competition with the likes of Skype and, to a lesser degree, Facebook.
It has also improved Hangouts for the web, including the addition of screen-sharing – you can now visually share and talk about Google Docs – and you can now name your Hangouts.
