If you designed the site, I would have you know that I kept clicking on the Sign Up button multiple times and thought it wasn’t working. Then I noticed the email input box with dark background blending into another section. Those were frustrating 45 seconds.
Apart from that, I fail to see its value proposition over Flipboard or countless other similar products. If anything, I want to see less personalized products. We all know what echo-chambers have been doing to us lately.
Very nice site design, though. :)
