Does Stackoverflow public dump of data and mirror sites affect its Page Rank?

Question

We started to see SO content duplicated in some sites. Does it affects SO position in Google results?

I'm unsure about the Page Rank, but the search result order is affected as Jeff posted here codinghorror.com/blog/2011/01/… — Jader Dias, Commented Jan 4, 2011 at 2:58

StackOverflow content was scraped and used on other sites well before the monthly data dumps started.

Anyways, does it affect its page rank?

If anything, it probably raises it because the license for the dump requires attribution.

As Joel said it should increase page rank since the content sites have links pointing away from their content and towards SO, but SO doesn't point back. If the links aren't rel="nofollow" page rank would be near zero. en.wikipedia.org/wiki/PageRank#Simplified_algorithm

http://stackmobile.com/ scraped entire network on SO sites and formatted them for mobile browser. Is this OK?

actually StackMobile uses the StackExchange API. stackapps.com/questions/36/…

OK, cool. So using API is not considered scraping, right?
