My company got an article written about it by this website. The page that has the article and links to my site is a PR2. I'm about to make a link pyramid using SeNuke XCR and want to diversify my tier 1 links. Planning on using web 2.0s, a wikipedia article, and high pr social book marks as my tier 1 links. My question is, should I include that PR2 article written about the company as a tier 1 link? Or should I leave it alone since it's already a PR2?
