If I had a good and understanable knowledge about a certain situation or thing then yes, I would share it with the world. I can posibly help pther or embrace others. Why not share knowledge that you as a person have gain something from. Its nothing that I can see someone losing because they shared knowledge with others in the world.

If I ever was to come across some really valuble information then yeah I would share it with others and I could be helpful to someone,probably not everyone but I believe it would do a small amount of people some good. Knowledge is cognition, the perception of reasoning and learning.
