8. It is no longer sufficient to simply master the technical. More and more, successful design requires a grounded understanding of why you are designing in the first place.

9. the maturing ecosystem a history lesson insights from the ecosystem iterating the developer mindset

10. history of the ecosystem what is past is prologue maturation of the Twitter ecosystem

42. valueless questions How much does the application need context? How quickly is the outcome from the interaction enjoyed? Is value created individually or through contributions of a user community? How open is the access to the interface (public vs. private)? How much does the application focus on Network, Content, or Profile? Is the intended use of the application Casual or Professional? Is value created from a single tweet or an aggregation of posts? Is the valued information reflected or calculated?

43. valueless questions Does the application maintain a historical context? How much does this tool support anonymity? Are users inherently part of other groups, such as by industry or geography? How visible is the process? Does the application service developers, authors, or consumers? What are the metrics needed to determine the value of use? How do those metrics influence use of Twitter and suggest behavior?

66. best practices don't store passwords (use OAuth) validate incoming data / FIEO (Filter Input, Escape Output) make requests over SSL let your users talk to you (security@yourapp.com) consider use of random tokens to prevent forgery (CSRF) cap repetitious interactions (i.e. logins) make use of activity logs
