This week, we dive deep on several design principles that will help you make better decisions when creating interfaces and interactions. In Follow-up, we discuss the etiquette of responding to recruiter emails, and in News, we cover Twitter's latest exploration into presence and status. And as always, we share a couple cool things, including an innovative basketball shoe and an updated personal site.

• Article: "Twitter tests new profile features, including presence indicators and ‘ice breakers’"

Listener Question:

• Dmitry Veremchuk (@d_ver on Twitter) asks: "Is there a limit to number of the side projects one takes on? Because personally, I am interested in animation, video editing, illustration, programming, photography, and many more things. Starting projects in all of these fields would be daunting and of a low quality."
