"The hitchhiker’s guide has this to say on the subject of Tumblr: avoid, if at all possible."
"Tumblr was very interesting," said Ford, "I behaved very oddly there." … "I took up being cruel to fans," he said airily. "But only," he added, "as a hobby."
"It is known that there are an infinite number of blogs, simply because there is an infinite amount of space for them to be in. However, not every one of them is active. Therefore, there must be a finite number of active blogs. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the blogs on Tumblr can be said to be zero. From this it follows that the population of the whole of Tumblr is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination."
"There is a theory which states that if ever anyone discovers exactly what Tumblr is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable."
"You must not reduce yourself to a puddle just because the person you like is afraid to swim and you are a fierce sea to them; because there will be someone who was born with love of the waves within their blood, and they will look at you with fear and respect."
