i'm a bit late, but sorry to hear about the re-waitlist everyone... but you all are going to great schools, so hopefully you won't take the Stanford waitlist that hard. I'm fully looking forward to a great time at Haas and have gotten over the Stanford ding a while now. For my Stanford "fix", I'll just go visit terry at those amazing GSB apartments (jealous...

)
Anyway, I tend to agree with kwam, the GREs are important, but no more or less important at Stanford than any top 10 school, otherwise, the top 10 schools wouldn't all have such close GMAT score averages.
As for "changing the world", I think it's a great goal for Stanford to have, whether their students end up at MC/PE/VC/IB mostly or not. At least they have been exposed to other classmates who are gung-ho about changing the world. I'm definitely fond of the Bay Area schools (Stanford and Haas) for both focusing a lot on Net Impact, Social Responsibility, Non-Profit, and "changing the world" career goals. So hopefully that culture ingrains itself into the students, even if their short term goals aren't directly related.
Now looking back, that may be why I didn't get in (other than my ancient age

). I don't think my essays really talked about "changing the world" as much as it should. Oh well, it's all history anyways, no need to cry over it.

Good luck to those staying on the waitlist, but if you don't get in, you are still going to wonderful schools and it's nothing to get down about!
