How to Build a Table; How to Change a Car’s Oil; How Cook a Turkey; search for these and you will find countless of YouTube videos on each of these topics. People share their knowledge in hopes that it will be helpful to others. As a result, lots of people know how to build tables, change oil, and cook turkeys.
