Okay, ladies and germs, for those of us who want to practice writing Chinese articles and/or translating from English into Chinese (not recommended for professional endeavors but very useful to learn Chinese!), the folks at zh.wikipedia.org are incredibly accomodating. I’ve been rummaging around there and there are a couple of things someone with a fairly good level of Chinese could do.
Reading material – obviously there are scads of articles on all sorts of topics. Whether there are factual errors or not (a common criticism of wikis) the Chinese is written by native speakers, and at least there is a wide variety available (and more daily).
Writing practice – I’ve begun translating one of the English wikipedia articles into Chinese for the zh: site and it’s better than lessons – you translate as much or as little as you want, and darned if there weren’t corrections made the same day. Plus, there’s a “history” function where you can compare any two historical versions of an article, which means you can very easily see what corrections were made to your Chinese version – the changes are in red and the versions are side by side.
If you haven’t used wikipedia it’s a bit daunting at first – hard to figure out where to find things and how to do things. Editing articles is straightforward enough, but stuff like finding templates, adding stuff to your user page, etc. I still haven’t figured out. But for broad reading and free editing of your Chinese writing, seems like you can’t beat it with a stick.
