Wiki Info
The concept of a Wiki Wiki (or 'wiki' for short) is that the quality of content rises when everyone is allowed, even encouraged, to author and refactor any page. Wikis don't work if people aren't bold. You've got to get out there and make those changes, correct that grammar, add those facts, and make that language precise. It's okay - it's what everyone expects. So you should never ask, "Why aren't these pages copyedited?" - you should just fix it. It does require some amount of politeness, but amazingly it works.
Let's be absolutely clear: if someone writes an inferior article or article stub, don't worry about their feelings. Correct it, add to it, and if it's a total waste of time, outright replace it with something better. That's the whole point of a wiki! And nothing's lost anyway - it's all kept in the page's version history, so can be recovered if need be. And of course, others will boldly and mercilessly edit what you write. Don't take it personally. They, like all of us, just want to make this wiki the best it can be.
