From the link: "I considered Ensure but found it much too expensive, low calorie, unpalatable, and an ingredient make up that was far from complete or optimal"
I have family ties into this industry, and quite frankly this comment is rather ignorant. Ensure is a brand range, with a lot of variation, some of which are, for example, extremely high in calories.
It is also worth noting that one of the uses of products like Ensure is to actually mix in with regular cooking, increasing the calorific and nutritional value of normal food.
Comparing existing products in the market with "Altavista", and Soylent with "Google" is also very disingenuous, as it serves to discredit all the work put into existing products, and ignores their business model. Funnily enough, Ensure isn't marketed as hipster-food, and everything about it is tailored for their target market of the medical industry.
As hackers, surely we should be supporting good business, rather than blindly going with the latest fad?
