Really enjoyed @PCampLDN, met some really interesting people and learnt some cool new stuff. My favourite three new things coming out of it: the viral co-efficient, the van Westendorp pricing model and the book "User Stories Applied". Reading up on them all now!
Product Managers and related folk from different industries getting together in interactive sessions on topics of their choice..... refreshingly effective! Well done to Janna as well for organising this first ProductCamp in London!
