Let's be honest: You're not a dummy.
Technologies are often designed to guard against the seemingly errant desires and mistakes of the commons. What's remarkable about this technology you intend to learn is its ability to immediately expose and evolve the true desires of the commons.
Although it may seem so, simple technologies like this don't happen over night. What looks like a story of 1 to 3 years actually has a shadow of over 15 years of work, dumb mistakes, false starts, late-night frenetic insight, and patient distillation. Twitter is a life's work built around three tenets: minimize thinking around communication, expose trends in local and global circles, and spark interaction. What you're holding in your hands describes an essence of communication upon which millions will build their own value.
While not everything can be conveyed in under 140 characters, the essence of Twitter can: "Expect the unexpected. Whenever possible, be the unexpected." I expect you to build something unexpected. Start small, start here.
