The websites that want you to share food

Internet technology, especially mobile, allows us to monitor our resources like never before - in theory making sharing more possible.
It is happening on both sides of the English Channel.
The website Cookening, wants you to turn your kitchen into a restaurant, inviting guests to take part in your meal. The start-up has almost 3,000 users, almost half of whom are in France.
The recent LeWeb conference, examined the sharing idea, which it called "Digital Hippydom" and it found that the French public and companies are particularly suited to the online, sharing economy.
Meanwhile in Britain, Crunchd uses apps to encourage people to share their experience of growing their own vegetables. It then allows users to trade their produce and create an online harvest for everyone to share.
