Growth Hacking Handbook: 100 tried & tested growth tactics

Hi everyone - surprised to see this up here! I crowdfunded this book last year (it raised about $13k USD in preorders), launched the finished book about a month after the campaign finished, and it's been out for just over a year now. I think the content is still pretty relevant to most tech startups, but definitely now I think there's an opportunity to get a bit more granular - if I had the time I'd launch the Growth Hacking Handbook for hardware, the Growth Hacking Handbook for mobile apps... etc (with collaborators, since I'm not an expert on either of those industries). If only there were more hours in the day :) More about last year's crowdfunding campaign here: http://yongfook.com/how-i-got-12...
