What is the simplest, quickest, least obtrusive wiki site out there?

I’m not getting this question, and am having difficulties relating “obtrusive: to wiki. Could you site a specific example that would make a traditional wiki site not a good choice?

Thanks for pointing out that that might not be clear.
Google Docs: If someone creates a document and shares it, anyone without a google account must first create one.
Wikispaces: It’s the best simple wise, but still everyone needs to create their account and the wiki has a discussion board, and other features a barebones wiki wouldn’t have I suppose.
…I was just wondering if there’s a wiki that is as barebones as can be with simple privacy.

So basically obtrusive is needing to create an account, having to find the specific wiki on the site, having lots of upload options, not know whether to edit the wiki or use the discussion board, etc…

You could just make your own wiki – there’s a site that tells you exactly how to do that.

Perhaps PBWiki will suit you.

I’m pretty sure that on PBWiki when you create a new wiki, you can make it open to the public, so that anyone can see/edit it. The wiki creator will need an account, but I don’t think the rest of the contributors do if it’s a public wiki. Good luck!

Why in the world would you want to put content out there and have random strangers be able to collaboratively edit, destroy or distort your content without identification?

Or corroboration?

I have used this method to allow users to modify lyrics on my lyrics site. Pretty much anyone can click on the lyrics and correct them. People spam it but I have some tools to prevent it.

If you only give the link to people you trust you should be fine. And use a robots.txt file so google doesn’t index it.

Thanks guys, I’ll try out pbwiki.
@johnpowell very cool, I’m bookmarking that.

I guess what I was originally looking for was something I stumbled upon awhile back. A site where you went, entered some notes and left. When you came back to the site it remembered who you were without an account and you could reedit or share your note.

@warpling, that description is very different than your question. Perhaps if you could provide a few more details about the site, then someone would recognize it. Was it specific to a certain type of subject matter?

@PandoraBoxx sorry I see how that seems different. I just meant it as an example of the simplicity I was looking for in a wiki. It’s just for figuring out who bringing what to a dorm. It should be simple, not require a log in, and not be something that is meant to stick around for a long time.
