How do you discover new books? Matteo Berlucchi is tired of buying books from a certain online retailer only to be recommended very similar reads. He tells us why his aNobii.com is different.

Charles Arthur sits in the presenter hotseat for this week's programme. He's joined by Josh Halliday and Michael Brunton-Spall to discuss the week's developments, including what Rupert Murdoch's supposed Twitter feed tells us about the verification process and why those network crashes on New Year's Eve look to be a thing of the past.

Plus, Aleks Krotoski talks to Chad Dickerson from vintage retailer Etsy about its rise and rise, and how to scale up a business without losing your customer focus.
