Many self taught developers will focus on less theoretical skills related to programming and focus on what's practical. They may read a textbook to teach themselves but it'll be different than the textbooks they make you read for a CS degree. This typically is a benefit, many fresh CS grades I've seen are not as comfortable developing in their first job as a lot of self taught developers.
