Students, as you begin blogging on a regular basis, the need to write cleanly is paramount if you want your audience to take you seriously. Readers will not follow someone they don't respect, or someone they see as unintelligent. Even a writer in sixth grade must produce good writing that makes sense, and is not filled with errors. Plus, the content must be interesting and engage the reader. But, that will not happen if the writing has basic errors that distract the reader.
