Mental notes to myself

I’m trying to understand how google handles the duplicate contents and wondering why some sites are luckier than others, almost having an immunity for duplicate content issues.
Some collective sites like answers.com is seems to be immune to the duplicate content penalties.
See this page about smokey bear(PR4). Correct me if I’m wrong but all I’m seeing is a rip of wikipedia page(PR6) along with lots and lots of advertisements.
Who can really say that this page benefits surfers when wikipedia page is exactly the same thing. I guess answers.com is taking this duplication tactics to the roof. Google is also helping them to drive traffic by hardlinking to their content as the “definition” reference.
I’m expecting no comments from Matt Cutts :), just thinking laudly.

I was checking for the Free Content category on DMOZ.org and I saw it’s updated. I also tried the check the google version. Big surprise! The category does not exist in google’s dmoz copy.

I’m not sure if this is on purpose, but it’s most likely that google is also moderating the biggest moderated directory on the net. Hehe that’s a good one.

See it yourself (I’m not sure for how long this links will be alive)
Dmoz link : updated around June 4th
Google’s Link: doesn’t exist as of June 5th

Also I’ve found if you search for url that exist on dmoz’s certain category, google returns a result but the link is simply for oh for.
See the first link.

Last notes: Yahoo’s directory doesn’t have the category too. I kind of understand it since the category is under Business branch and it’s a paid service for yahoo to appear under that branch.
