Apparently Stephen Hillenburg has a Twitter account, and if you look through his list of people he's following, almost all them are people who worked on Regular Show, Adventure Time, Steven Universe, and even Cartoon Network itself.

And yes this is his real account because Paul Tibbitt mentioned him

(He's also following a Smosh page but that could be because he worked for Shut Up cartoons) I always thought Steve wasn't really into anything "Hip" and "Cool" or "Trendy". It seems like he's slowly getting over that. He isn't even following anyone from Nickelodeon. Also I noticed that Sponge Out Of Water had a bit more of an edgier story. The show has changed a lot since he's came back to be honest.
