While users are encouraged to be bold and edit freely, not all edits are equal. For instance, edits may introduce bad advice or erroneous information, and this should be removed. Since many articles contain matters of both fact and opinion, disputes about notes, trivia, or other content will inevitably occur. If your edit has been removed, use the article's talk page to discuss the information in question, and why it was removed or readded. Explain what you think about the info, and why you think that. As long as general consensus is reached, the edit(s) in question will be restored/deleted. With the proper use of talk pages, many conflicts can be resolved peacefully- and without a revert war.
