The site is very nicely coming along.
However, I worry about its future. There's all kinds of content on that site that is attributed to a wide variety of people - it's certainly not public domain - look at all the pictures and the copyrights reserved, and there's no clear policy regarding the submission of content and who owns it or what is "legal use". At some point in time, whoever is running that site can take it down just like the pinrepair.com site, pinwiki will be mired in controversy, but in the case of Pinwiki, people will actually have a legitimate beef because that site IS created by a bunch of people, whereas Pinrepair.com was the result of one central editor who wrote 99.9% of the content and actually has legitimate rights to it. So, while Pinwiki is nice... it's not like Wikipedia where submissions are supposed to be public domain or specific types of unrestricted licenses.
I am not sure what's going to happen in the future with Pinwiki... what happens when someone takes some of the content and tries to republish it? What happens when the web host guy decides hes tired of paying for the hosting and brings the web site down or monetizes it? What happens when people in the community start fighting over who "owns" what parts of it? It's something to think about.
