Hi,
I want to share this nice method to get links from wikipedia, maybe some of you know it but it can help those who don't, because wiki links are great to climb in serps even if they are Nof0ll0w.
So in fact you have to search for wikipedia "discussions" with this footprint : inurl:"http://en.wikipedia.org/wiki/Talk" "keyword"Then select discussions pages which are empty, to be sure noone will come and delete your post, and let your link.
Enjoy!!
I have spread many links on wiki with this technique and I noticed great improvements in serps.
