When creating a web page, a Wikipedia page, an Everything 2 writeup, or any other hyperlinked document, do not just link every single word; this becomes annoying rather quickly. Don't just randomly sprinkle brackets around words either. Make sure a link implies some clear association between the page you create and the page you link to. If you mention something more than once, don't link a word or phrase every time it appears; this gets boring.
