So you just learned about Wealthfront and Betterment today and somehow you've determined that Betterment is "utterly awesome" and Wealthfront isn't? I hope that whatever your role in finance, it isn't related to due diligence.
I might've been a bit too black-and-white with my comment, let me clarify...
Betterment seems utterly awesome. Truly a product I'd expect to see from an innovative fintech startup. Wealthfront did not.
It was clear that Betterment cared about making a beautiful consumer-driven product. It was also clear that they've spent some time reimagining how personal finance works. Simplifying it.
I also can't help but note that the fact that Betterment made me so excited (it really did) so quickly probably speaks very well of it. But then again, I'm a sample of 1.
(Incidentally, I read your HN profile and rather liked the story in your 'about')
