“Unlike blogging, where you spend time thinking carefully about what you say in each post, Tumblr is really more about the moment of consciousness, and capturing a snapshot of it. Hence, where blog posts are supposed to be solid and stand-alone, Tumblr posts stand in relation to an entire thread of posts. That’s why looking at a Tumblr page is like taking a peek into a person’s stream of consciousness.”
