The reason a lot of people want that is they want a passive income to give them security.
Given the success of instapaper and the fact he'll have done fine out of Tumblr, I suspect Marco has no need for that and would rather devote his time and attention (something can be distracting even while taking little actual time) to something he'd be happier doing.
Definitely interesting, but would love to see some results other than leafy greens and basil. From what I know (farmed in Vancouver, BC) neither have much disease pressure, nor require much manual attention.
If an initial goal is to increase local produce for winter months in cooler climates (than California) then seeing tomatoes, summer squash, and fruits seems necessary. I think berries could be confined to the small space, but what about fruit trees? I personally store (preserve or freeze) berries and peaches to have in winter.
Kale and other leafy's can be over-wintered with much cheaper (to build and operate) green or hoop houses – at least in the pacific northwest.
I understand they are in the MVP kinda stage, but to me, to see any potential value I would need to know if fruit, tomatoes, summer squash can be done in winter, as those require more heat, more sun, and have higher disease pressure.
I agree that Windows lacks a good shell. But Git is easy under Windows7 and Powershell. It's the one of the few tools that was easily installed and usable under Windows. (Though Rails and Node have joined the ranks recently).
Which concludes: "We suggest that any real declines are generally most easily explained by changes in cultivated varieties between 1950 and 1999, in which there may be trade-offs between yield and nutrient content."
