What is a major difference between the poetry of emily dickinson and the poetry of walt whitman?

Emily Dickinson and Walt Whitman are poets that are considered to be founders of Modern American poetry. However, like any other great poets, there are differences in their poetry. An example would be the introversion of Dickinson's poems and the extroversion of Whitman's poems. Dickinson's poems are simple and unique due to her odd placement of punctuation, unusual grammar and simplicity of language while Whitman's poems uses free verse. They are complex and long, more profound than Dickinson's and uses the "taboo" subjects like sex.
