From infancy, humans understand the direct connection between communication and survival. Before we learn our first word, we perfect the art of getting our physical needs met through whatever vocal abilities we can muster. Later, curiosity about our environment and a strong desire to be understood drive us to master language skills.
We want to be heard and we want to be relevant within our community.
Social media has become the vehicle that powers two-way conversations across time zones and over borders. Even language differences are no longer a barrier with the availability of free tools such as Google Translate and BabelFish.
We inform. We learn. We debate. We might even argue. The point is, everyone has a chance to be heard.
