This is exactly the kind of information that is valuable, pertinent, and helpful to star-uppers. Not only that, but I love how the article foregoes mumbo-jumbo and goes straight to the stats and numbers. +1 to you, sir.
Coming from a recent failed bootstrapped start-up, this is both encouraging and motivating! It's hard out there, but it's good to see people achieve even a moderate level of success.
I personally would also like to see more transparency among founders.
I think there's a fear among entrepreneurs that if they post their data publicly, one of two things will happen:
(a) they'll be judged if they're not succeeding wildly -- its easy for startup founders to seem glamorous when there's a fantasy that they're just living the startup dream (which, at least in my experience, most of us aren't just rolling in rooms full of gold coins). without the certainty that they're not succeeding wildly, founders can bask in the adoration of their unknowing peers and reap the rewards of semi-fame without the actual success.
(b) if they ARE succeeding wildly, that competitors will know how much money they're making/losing -- this information has never helped anyone. knowing that RL makes $X doesn't immediately make my competitors make $X. RL has succeeded, I think, mostly because I'm willing to work hard, and not because I'm tricky or smart or have some magic silver bullet.
I, for example, would like to have sex with Heidi Klum. Finding out that Seal is having sex with Heidi Klum does not confer upon me the privilege of doing so. Knowing that a startup is making money won't make it true for you.
