I'm a tree. Only in Puzzling Stack Exchange. I'm a book about a tree in Literature Stack Exchange.
Also, blame Rand al'Thor. And also blame Tsundoku.

My favorite quotes from my time at PSE:

"A certain level of stupidity is impossible to differentiate from genius...." Mithical

"...the corollary being that a certain level of genius is impossible to differentiate from stupidity. Mithical

"Eat sh&$ and die. On a good day." humn

"Oh, I've been kidnapped again." Deusovi

"I don't need two arms to kick your ass." Sciborg

Please note that I look nothing like the photo above, it just happens so that ash trees are the most generic looking trees in the world.
