The Best Vocabulary to use in blogging

My personal definition of a blog is a piece of writting about a particular topic which is "UNDERSTANDABLE ".a blogger is supposed to use simple and undersrandable words in his essay to avoid any complications in the reader.After your blog is read,the reader is supposed to understand every single information you want to share with him or her.A good blogger should also never deviate from his topic.If your blog is read and no understanding comes out of it,it's no more a blog it is just a piece of "shit".
