From what I can see, the site centers on refining an investor’s allocation between equities and bonds. All those wonderful web 2.0 elements are dedicated to this allocation question. For example, as the demo explains, you can see how a woman aged 30-something allocates her investments.

It’s a nice idea — assuming that women aged 30-something know how to allocate their investments.

But I have another issue with Betterment. I just don’t want to give it my very, very personal information. I went through the sign-up process and I had to wonder why and to whom I was giving my Social Security number. Is the site safe? Who knows? I mean, who knows who Betterment is. For now, I’ll allocate my investments without the help of women aged 30-something.
