Knowledge increases in multiple ways when it is shared. Sharing what you know helps you learn by doing research, synthesizing multiple viewpoints, and crystallizing ideas, thus increasing your knowledge. When you share, it gets others to also share, which increases the total body of knowledge.
Absolutely. The best way to learn is to teach. This is from my personal experience teaching college courses for years. There is an ancient Eastern saying, "knowledge is the only resource that increases the more you give it away," which is so true. It is further stated that knowledge is more powerful than even wealth since a thief cannot steal the former away but the latter since the latter is in plain sight.

I agree fully with Hassan Izzeddin Sarsak. Sharing knowledge leads to the growth and transformation of knowledge which ultimately creates and contributes to the wealth of knowledge. Knowledge kept to ones self provides no contribution.
