Tumblr is one of the world's most frequented sites, boasting 109 million blogs and 51 billion posts, allowing users from all over the world to share the odd, the quirky and the interesting. Our Trending Tumblrs book features nine of our favourite Tumblrs – from Ca$h Cats to Goths Up Trees. Where else could such diverse content sit under the same umbrella? We hope this book provides you with a few laughs, some fresh thinking and perhaps even some inspiration to go Tumbl.
