Enh, it depends here. Some people do, some people don't.
I go more for context than art skill. If you have a lot of drawing skill, but can't design an original character, or your whole dA gallery is filled with painstakingly illustrated drawings of Hitler, I'm NOT a fan of you. I'd honestly much rather watch an artist who can't draw as well, but has a lot of great ideas, even if they can't always execute them. My brother doodles on the side (I can't tell what, if any style he has yet), but my sister likes more realistic portraits or Alphonse Mucha art nouveau stuff.
I did see one classmate that drew vaguely anime-ish cat-eared Hunter x Smoker slash from Left4Dead, and I just decided to leave her alone about it. In time she'll draw better things, look back on those drawings, and laugh.
