A good article on Wikipedia should be readable—easy to read. Poor sentence structure and wordiness can annoy readers and even frustrate them, rendering some articles inconvenient to read, some to the extent of being virtually unreadable. Other impediments to readability include excessive numbers of warning boxes, long lists within an article that make readers not want to continue scrolling down the page, excessively long external link sections, and styles that decrease reader's interest, among others.
