Reddit is incredible. In biological terms, it’s one of the Internet’s arteries. It has humour, character, seriousness and solemnity – and much more besides.

It should come as no surprise that the site’s co-founder, Alexis Ohanian has written a book with the same characteristics. Without their permission is at once funny, informative and touching. Writing conversationally is a difficult trick to pull off, but in Ohanian’s case, he does it with aplomb.

Expect lots of brilliant advice, interesting anecdotes and nods to pop culture in a book that is both a memoir of his time at Y Combinator, Reddit and Hipmunk and a how-to guide for startups.

If you’re have a passing interest in where the Internet is going, you’re going to want to read this. The best books are the ones where I’m left with notes after reading. This generated pages of them.  Enjoy.
