Dropping Knowledge is a website that a friend of mine shared that is similar to the Edge. It is a collection of thought provoking questions that are open to the public allowing them to chime in with their insightful thoughts. You could learn a thing or two from reading all the responses. You can even pose some questions yourself.
If you don't know, now you know. The Khan Academy, (founder Salman Khan, not to be confused with the terrible Bollywood star of the same name) seeks to improve the quality of education through online internet courses that are free and available to all with an internet connection. If you have an internet connection then welcome to the wealth of knowledge that is available to you. From vector calculus to banking to oncology. Welcome to the Education Revolution.
Inspired by this idea of making the world a better place through critical thinking, The Dynasty emerged organically while I was in college. Friends would get together on Friday and Saturday nights at a local coffee shop to talk about issues and topics of great depth. Not wanting our conversations to go in vain, we vowed to continue these conversations outside of the coffee shop with others. Once we all graduated from school, we now hold our discussion sessions via email. A new question is sent out every month and by the end of the month all the contributions are anonymously put up on the site. We, too, hope to contribute a small portion to the Education Revolution.
