I found this great chart on thoughtcatalog.com which highlights the differences between Shy and Introverted and between Extroverted and Obnoxious.
This addresses many of the misconceptions people have about other peoples personality types. For example, many people, especially extroverts, seem to think that shy and introverted mean the same thing, whereas they are quite different reasons for being quiet. The same is also true from the other side though: many introverts mistakenly assume that all extroverts are annoying, but this is not true.
