Matt seems to be very acclaimed, since when people saw him at a comic convention, everyone went for him for an autograph. Matt told them they can also take a bit of his 'stache, as they say it's good luck. However, when Homer sees a drawing of Bongo the Rabbit by Matt Groening (from his comic Life in Hell) he says Matt is not even a good artist. He was once hired to draw a caricature of Freddy Quimby in a trial. When Kent Brockman presented a list of people who are gay, Groening was on the list.
According to Channel 6, Matt Groening is gay, as he appears in a list in which all gay people appear. He is also in Comic Book Guy's banned list in the Android's Dungeon & Baseball Card Shop, along with Sideshow Bob, Nelson, Bart and Milhouse.
