Wonderful idea from the Guardian in the UK. They have decided to open a dedicated crowd sourced news hub called GuardianWitness. The public provide the content and the Guardian team do the editing, as well as help to provide some guidelines for the content.
To provide content or read the latest stories all you need to do is go to https://witness.guardian.co.uk/. On the site, if you want to contribute you can download a custom app for iPhone, or Android phones, this will allow you to upload pictures, video, and text. Popular content will stand a chance of being published across their main news hubs.
Will be interesting to see how this idea pans out.
