This is a PR 10 list. Some might have been downgraded to PR9. http://www.google.com http://www.statcounter.com http://www.adobe.com/products/acrobat/readstep2.html http://www.nytimes.com http://www.adobe.com http://www.firstgov.gov http://www.apple.com http://www.apple.com/quicktime/download/ http://www.real.com http://www.w3.org http://www.nasa.gov http://www.macromedia.com http://www.apple.com/quicktime http://www.nsf.gov http://www.energy.gov http://www.mac.com http://www.apple.com/retail/ http://web.mit.edu http://www.harvard.edu http://www.webstandards.org http://www.keio.ac.jp http://www.lcs.mit.edu http://www.microsoft.com Code (markup):
Just because Google doesn't count your Yahoo Answer as a backlink, it's still a good way to get traffic. Also, if it provides a good resource people will bookmark it on delicious, stumble, etc.
However, it would be nice if you could advertise on them. I am working on that right now with http://www.isrchnkd.com. I will have around 800 links on the new update. We should be a PR 6 at the new update on the homepage and page 1 link. We are having people exchange links on relevant keyword phrase pages. You can do a max of three for free. We would like you to link to us. That is part of the partner rewards and the link exchange tab. I am working on building up the pages to a PR 9 at this time, but it will take some time to do this. We are working out some bugs right now. I don't see any other way to help others out. I am not concerned about getting advertisers at this time as much as getting the PR and traffic higher. I hope this helps people in the future.
if only know which site is pr9, is not the point , i want to know which pr9 site give us a free back links
There is no PR 9 site that will give you a free backlink. That would not be smart on their part. One, you would have to be lucky to advertise on that PR 9 site and secondly, they are not going to just let anyone advertise on that site.
