Untangling the web with Aleks Krotoski

How has the most revolutionary innovation of our time - the internet - transformed our world? What does it mean for the modern family? How has it changed our concepts of privacy? Of celebrity? Of love, sex and hate?

The online version of Untangling the Web is the collection of interviews, links, photos, videos and brainstorms that feed into Aleks Krotoski's fortnightly Observer column. Every other Sunday, the next topic will be revealed. Feel free to contribute your ideas on each in the comments of the blog post, by email to aleks.krotoski.freelance@guardian.co.uk or via Twitter, by tagging your tweets with #UTTW or @aleksk.
