Based on that data an average minter makes at least $4,100 x 12 * 1.33(to account for taxes) = $65,436...and thats specific spending, who knows what % of their income gets saved or invested.
So thats the 10% or so of the population who are well off, what about all those people making less than 70-80K?
Yes, that might introduce biases in their data that don't reflect with high fidelity the entire breadth of consumer actions, but even slightly imperfect data that's internally consistent can be quite valuable.

To be fair he might have been displaying the median income and husbands and wives might have separate mint.com accounts, although I would be surprised if the typical behavior was to divide the cars and mortgage between two accounts.
Edit: looks like sokoloff and I thought the same thing at the same time
Mint is also a money management site, so by it's very nature it's users are interested in properly managing their money. People who care about proper money management are probably doing a better job of making/saving/investing it.
My life experience is limited (I'm only 24) but from it I can say with confidence that the majority of people in my community, family, school, etc are not tech savvy, don't worry about managing money, and frankly most still believe that if you can't buy the software at bestbuy or walmart it's not made by a reputable company.
Having such a huge sample means that the data does at least mean something. It does indeed tell us something about the habits of those likely to sign up for that service, after all. It's just that converting that to the universal data we're all really interested in is non-trivial, and if the bias is strong enough, basically impossible if the projection of the noise dominates the signal.
(In other news, this article worked. I'm seriously considering signing up. :) Informative marketing, the best kind.)
It's mighty hard to draw conclusions from one year's worth of data. We see consumer spending spiking again in December. Is it Christmas (.com), or is it a recovery?
