Making Nyarlathotep's adaptation as a "meme god" is SO in character.
A cosmic horror, who embodies the chaos itself ("the crawling chaos") and is relatively amicable to & interested in human beings, having a knack for actively creating & partaking in memes makes so much sense.
Since memes, in nature, are very chaotic & deeply reflect the human culture with high temporal resolution (or simply, it is very time sensitive).
