Zemanta is partnering with Federated Media to provide a sponsored post advertising opportunity to bloggers. From the few examples I reviewed, they are complying with FTC recommendations for disclosure as well as Google recommendations for not passing PageRank. The links are redirects through a domain that is blocked to bots by a robots.txt, so the links won't pass PageRank. That's Google friendly, white hat and above board.
Zemanta is an authoring tool for Wordpress, a plug-in that helps bloggers in their writing. Federated Media is a company founded by John Battelle, a man who is extremely knowledgeable about Google and who actually wrote a book about Google. He also founded Wired and The Industry Standard.
If anyone is looking for a paid links scheme under the covers they're not going to find it here. I have not done business with either of these two companies, so I don't have a conflict of interest. I would be the first to call BS on it if the aroma was there. But it's not, as far as I can tell.
