I've started filling in a few pages on the Apache wiki: http://wiki.apache.org/hadoop/ZooKeeper
In general the Hadoop structure looks good, I plan to follow that where it makes sense. There are a number of pages that need to be moved over from SF, however there are some pages which are more suited as documentation, and those will be added to svn under trunk/src/docs (need to be converted to forrest compatible format).
If anyone has comments let me know. I'll be moving the pages over the next few days, after which we should be in good shape to start "turning off the lights" over at SF. Doug tells me there is a way to convert the SF site to "readonly" mode, where we point ppl to the apache site.
There are a few new pages I added like "PoweredBy" and "FAQ" that you'll see on the ZK wiki frontpage (link above), feel free to start filling those in.
