How to Make a Killer Wiki Page
Creating a killer wiki page is very much like designing any other web page (or any other document, for that matter). A little extra thought and care you put into the page, the better and more usable that page will be.
A common mistake is to simply paste in a bunch of content from another source and click save. This often makes a page that's harder to read because much of the formatting may not have been preserved in translation (so you may get a giant page with no paragraph breaks, or your bulleted lists disappeared, etc). This would be like sending a client an document written in notepad.exe. A little formatting can go a long way in making a page more readable.
Similarly, don't let your page become a "dead-end" because there are no links to go to related pages. Wiki pages are just regular web pages-- they should almost always have links to related information within the wiki or even to a related site on the Internet.
Every wiki page should follow these simple guidelines:
Title your page - Don't make people guess what your page is about. The first line should be the subject/title of the page, and it should be in the nice big Heading 1 font (look under the "Format" menu on the edit bar).
Include a back link - If your page is a sub-page of another page, add a back-link just under the title so the reader can easily get back to the relevant page. Nothing is more annoying then having to click the 'FrontPage' tab and drill back down to where you were. For example, just under your title add code like this [:OriginalPage:<< Back to the OriginalPage] where OriginalPage is the page your page is linked from.
Label Your Sections - In long documents, each section should be labeled in a heading font - In other words, don't just make it bold and underlined. There's a very good reason for this-- table of contents (more on this in a bit).
Increase Readability - Just like any other document, you can change the readability with just a little diligent use of formatting, such as italics, bold, or underline (or combinations thereof).
Make a "Related Links" section - If you are making a series of related documents, don't make people guess or hunt for those pages. Don't make your document a "dead-end"-- cross-link with abandon!
