Sometimes it just seems like we experience a series of similar events that are so unlikely that it feels like more than mere coincidence. A bunch of people who don't even know each other decide that "today is the day" to take some action. Even C.G. Jung spent a good deal of time studying the idea of "meaningful coincidences," and how they were tied together.
As for Steemit, I'm part of that same group who believe there's something really good and promising "buried" here.
