It looks like you're focused on definitions? Great. For an example of a great definition page, take a look at http://www.wikinvest.com/wiki/52_week_high. You'll see they're using sections headers, bold, etc. to make the content more easily readable. It's just something to think about as you're making edits to the site.
Also, if you're looking for a general set of guidelines, check out our Guide to Writing.
Hope that helps. Feel free to reach out if you have any questions about Wikinvest.
