I love this product, the design is great, and it serves a great cause. It had a huge impact on my usage of facebook and other websites I was addicted to. And while most of the chrome extensions are pretty impersonal (you don't even know who built them) - the author posts a lot on Medium, to share updates made to the Nudge product, or just to share how much he cares about time well spent, and tries to raise awareness about those companies built and designed to catch your attention, and maximise the amount of time you spend using their products.
