==Regarding my edits==
I like creating practical content such as "guide" pages that help me when I play, indexes/tables that have a purpose such as [[Belt|a list of the lucky belts]]. I don't think it's very useful right now (as of the alpha) to create many individual pages for mobs/plants/items (exception for named creatures, and category types like goblins).
If a player /wiki a specific item or foe that does not have his own page, that's not an issue imho. They will get search results and relevant articles. For example <code>/wiki snail shells</code> will show NPCs interested in snail shells.
So atm I focus on: NPCs, Zones, Dungeons, Skills, Special (ie. named) creatures and Bosses, and "guide" pages.
* I use a <code><nowiki>__NOTOC__</nowiki></code> for most pages that I don't expect to be long. People are accustomed to mouse wheels, and the TOC tends to make the top of the article look bad with a lot of white space (a solution would be to float the TOC to the right in some pages, that may be doable with a template). The <code><nowiki>__NOTOC__</nowiki></code> marker can always be removed later if something gets long enough.
