Oekaki@Heyuri

Why are Western oekaki communities posting like this?

They're not all like this 139-san, it's just that Heyuri is more of a "having fun on the Internet" community than a Serious Business art community (although we have had real artists™ here before, honest!)

Here's some Western oekaki sites that take things a little more seriously:
