But are you measuring the effects of the tweaks? That's the whole point of A/B testing. The whole "good and interesting information" vs "beautiful graphics" division is a false dilemma. You don't have to choose between them. And, I'm not even saying that you should have "beautiful graphics". What I am saying is: you are running a business here. The goal is to make money. There are tools (notably A/B testing) which will make you far more effective at reaching your goals than you currently are. You're getting lots of valuable (but free) advice from the good folks of HN. It would behoove you to take it seriously.
