To add social networking features to any web site, you can get code from Google (although, unfortunately, the site does not work until tonight) and pick which features you want to add. The code will allow people register on your site, invite other people, import friends lists, see who else is on the site, and post messages and reviews.
According to their press release: “Visitors to any site using Google Friend Connect will be able to see, invite, and interact with new friends, or, using secure authorization APIs, with existing friends from social sites on the web, including Facebook, Google Talk, hi5, orkut, Plaxo, and more.”
So, Marketing Pilgrim could add some features without hiring a programmer. While it won’t be a full-blown social network, you could see other Marketing Pilgrim readers and interact with them with one login. That’s the idea.
Friend Connect will work with existing standards such as OpenID, OAuth, OpenSocial, as well as with data access APIs from Facebook, Google, and MySpace. The sites are trying to compete in becoming the repository of information from which other sites draw from.
Google Friend Connect is in a preview release and will start with a group of sites that Google has picked.
