I respectfully disagree on revenue - it's also largely a vanity metric. I know it doesn't feel that way (especially when there is little of it), but think about the seasonality problems and all the things that may compete for users attention like the Olympics. Revenue is a good indicator over several months, but it's largely useless for day-to-day decision making. Far more useful metrics would be engagement among the people who have proven to be the core audience, likelyhood to recommend the product to others, time-to-first-satisfactory-outcome, feature use frequency. I am contemplating a diabolical plan of turning features off and measuring the relative frustration rates.
