Test-n-Tell - tiny apps, Big ideas

  Nir Eyal’s Hooked made a huge impression on me. It shaped a large part of how I think about product creation. Not because I wanted to “hook” users at any cost, but because the book made one thing very clear: if you understand how to influence behaviour, you also become responsible for how you use that power.

or you would know what I've just learned  Product psychology, simplified I came across Nir's blog a few weeks ago and was "hooked" since. Nir writes about products, business, and psychology. Writes really well, not only informative but also very engaging, with lots of examples and practical advises. If you're building products, especially technology products, then this blog is a must-read for you.
