Most of the popular artists I watch/talk to on DA are really kind individuals. Most of them are college students and often seem arrogant due to their busy schedules. There are a few that are ignorant, but popularity doesn't automatically make an artist arrogant or snobbish. Some pf them draw for fun/leisure. Some draw for a little extra cash. The common thing I read when they post their journals is that they appreciate the comments and pageviews, and more often than not, ask for forgiveness for not being able to reply to the messages (although they're read).
