I feel that the dark could be considered the unknown, or even confusion. I may have not been on this website for long, however it seems to emphasize respectful and intellectual discussion, which indicates to me that by "pushing back the dark", hubski is providing a platform to which people can challenge themselves with new mindsets, ideas, and stories of others.

So I guess a simple summary would be that my "dark" is my sense of what is unknown. I push it back by craving new knowledge and stories of different life experiences, which possibly help me clear up confusion in my own life.
