This guideline recalls that there are three ways to cite sources. I do not like Citation templates, as they make very complex edit pages and are more bother than anything else. You can achieve exactly the same result without taking so much place on the edit page. In particular, they are not appropriate to face link rot. I hate the practice of deleting a newspaper source because the link doesn't work any more. You can't delete past history: the article still exists, and the link should be removed without deleting the source.
WP:TRITE: Use clear, concise sentences. We are not writing a novel.
Wikipedia:Only make links that are relevant to the context It is tiring to see all country names wikilinked ten times, when you perfectly know that 0,0001% of the reader is going to click on, say, the United States. If you really need to look information on the US, you surely can Google "United States" up and find the relevant Wiki page.
So, healthy dose of scepticism, as always should we add, and also, when you find something really interesting, be sure to make a permanent link (as done immediately above) or even copy it into your personal files. And, more important than anything else, be sure to check Reliable sources, and Cite sources, as well as Wikipedia:Footnotes on how to set them up.Post a message here (I will adress content dispute on the relevant talk pages, but you might want to let me know by leaving me a post if you're in a hurry for the answer).
