Facebook wants to turn every member into a spokesman for its advertisers. Mark Zuckerberg, the founder and chief executive of the superhot social network, today announced what the company calls “social ads.”

The ads expand what has been one of the most powerful features of Facebook, the news feed, where members see a list of what their friends are doing  photos from their parties, new friends, favorite bands and so on.

Facebook now will give advertisers the ability to create their own profile pages on its system that will let users identify themselves as fans of a product. Each user’s news feed will contain items like “Bobby Smith is now a fan of Toyota Prius.”

News feeds can be linked to outside Web sites as well, so users can tell friends about what they rented at Blockbuster or are auctioning on eBay.
