This is an excellent point. I find it interesting that so many things that I use in my own life for orientation are not even noticed by a broad section of humanity. Philosophy, technology, religion, politics, these are often monumental issues to certain people while rarely even noticed by others. It's interesting that the human experience is so diverse especially intellectually. It's hard to escape the belief that what I follow is IMPORTANT though. As well as the follow up thoughts of "If only more people paid more attention to X the world would be a better place...".
