(Real World + Semantic Knowledge + Internet) * Cool Technology = Awesomeness, have a look..
I love these broad concepts of the semantic knowledge, communal knowledge, user-empowerment all mixed with the web and real-world using "human-oriented" technologies.. It's the future, and we are already on that road with things like twitter (chatter), touch, wikis, semantic-web, xml, google etc. What is also interesting and relevant is how we are gonna bridge the gap between structured and un-structured information. It is all so fascinating stuff, but for now let me unceremoniously put it under the "cool" tag..
