I happened across a social site that has articles written by members which are also rated by members.

There are various categories for the articles, and I've noticed that the authors insert anchor text links back to their sites for various keywords.

The links don't have nofollow attributes, the site itself is a PR6, although the articles have no PR.

I was trying to figure out just how the site owners made any money, and then I noticed that there were Amazon ads in the middle of the articles, ads that pertained to the articles' topics.

The whole subject of blog links and social site links is new to me, so I'd appreciate any further comments.
