Satire in literature is the use of literary devices(most often irony) to parody errors, usually human vices in order to expose and correct them. A satirical piece can convey a variety of emotions but usually invokes humor.
Taylor Mali's "The impotence of proofreading" is a satirical piece making fun of people who rely on spell check. This can be immediately recognized upon reading the title. Take notice to the way the word "impotence" has been used to replace "importance". It's not exactly a mistake that's easy to make. The first paragraph ends with the sentence "Proofreading your peppers is a matter of the the utmost impotence.", claiming that one should always make sure that their work contains no errors yet two blatantly obvious errors come in the form of "peppers"(meant to be "papers") and "impotence"(meant to be "importance"). The author has clearly taken on the role of a clumsy pseudo-intellectual in order to, in a sense, give a "slap to the face" of those who find themselves having to use spell check a little too often. If the message gets across to readers, they will hopefully start educating themselves a little bit more so that they can correct themselves every time they make a simple spelling error instead of relying on spell check. ffffffffuuuuuuuuuuuuuuuuuuccccccccccccckkkkkkkkkkkkkkkkkkkkkkkkkk
