The poll and graphic were produced by Grammarly, the world's leading automated proofreader. Using elite natural language processing technology, it checks writing for more than 250 types of spelling, grammar, and punctuation errors, enhances vocabulary usage, and suggests citations. Grammarly delivers a passive learning experience that identifies writing patterns and sends users personal recommendations to help understand their most common mistakes and opportunities to develop their writing skills. Grammarly is also the creator of GrammoWriMo, a collaborative writing project to celebrate National Novel Writing Month (November). Last year the project brought together more than 300 writers from 27 countries to create a group novel, which was then sold as an e-book on Amazon and benefitted the Make-A-Wish Foundation.
