There are three ways to contribute on Big One is to submit your own original statement or question to start the conversation. Your idea will then be open to debate on the site. This is your chance to test your ideas against the world. You can also respond to the statements and questions of other users. When you respond to an idea, you will join a running conversation thread. Or you can submit a comment if you’re not ready to jump right into fray, but still have something to say. Comments on Big Think function much like they do on any other site; they give you a chance to share your thoughts as a spectator rather than as a participant.
