Thanks for the feedback. I've been constantly tweaking the black/blue and will obviously need to keep tweaking to find a better fit. And I will definitely add some hover states!
I have definitely struggled with the product's core value prop. Our biggest advantage over insights is that it's near real time, and is provided over time by post. We also allow you to track other blogs that are not your own for comparison. I will go back and make sure that that point is made more of a focus. Thanks again for your feedback!
