Some of this advice is really good, but some of it is terrible. The section on gamifying user interaction is absolute garbage. I'm not "80% done filling in my LinkedIn Profile." I'm 100% done, but LinkedIn just wants me to give it more for its benefit. I will never give it the remaining information. It isn't encouraging me to do the remaining 20%, it's just annoying me that LinkedIn can't take "No" for an answer. Also, I object to breaking the interface down into "screens". It encourages creating modal apps. Thinking about working in Photoshop, for example, while there are modes that depend on the tool you're using, you aren't in a different screen for every thing you're doing. (In fact, Lightroom does sort of have that problem, and it's why I don't use Lightroom.)
