About

Averagecats.com is a single-topic blog that catalogues image macros similar to lolcats, but the text is written to be a matter-of-fact explanation of the image; antithetical to lolcats.

Lolcats use funny pictures of cats with weird, misspelled captions, where Average Cats images consists of literal translations of the image, similar to Buzzkilling, and to a lesser extent Literal Music Videos.

AverageCats.com was created and is maintained by the same people as MylifeisAverage.com, on which they do not list their names.

Quote from the FAQ:

Who's behind mylifeisaverage.com?

We are. We are assisted by computers, food, water, and tiny amounts of sleep. Also by a diligent team of monkeys specially trained to replace the pronoun "i" with "I".

At this point it would appear that most of the images have been created entirely for this single topic blog. Finding instances of this in other forums in order to trace any spread.
