Grammar and Spelling:

When writing for your site, grammar and spelling should be correct. Likewise, when reviewing other people's additions, make sure they are using proper English and that their spelling and grammar are correct. Should you be insanely picky about commas and semicolons? Well, it wouldn't hurt to take care of the obvious issues. Read more about editing and judgment calls.

Tone:

The tone of your wiki will depend on what subject is being written about. For instance, Wetpaint's wikiCancer has a much different tone than Brickiwiki. In general, however, your tone should be upbeat and friendly, as all of the Wetpaint sites are about building an online community. While one site may be more serious in topic, it should still have the same warmth as a topic that is silly in nature.

Readability:

All of your content should be neat, clean and easy to read. Make your writing conversational, but not casual. Try to steer clear of slang and you should definitely not use profanity, but plain English with an active voice (in third person) is good. Also, break everything into short paragraphs, as that makes the information easier to process by visitors. Use of headlines, bold and italics also helps to make your copy easy to read. Keep in mind that people scan when they read on the Internet, so this is not the time to try out your extensive vocabulary with the use of pretentious language.
