The BlogNetworking plugin combines two simple but necessary components of any blog network: the ability to automatically create a blogroll in the sidebar and to show the latest headlines from across the blog network.
You can see the BlogNetworking plugin live in action at the bottom of the Soccerlens.com sidebar (under ‘Network Headlines’).
The plugin uses a central feed of network sites to pull headlines and display them on your site. The easiest way to do this is to use the blogroll opml of any one site in your network (http://yourblog.com/wp-links-opml.php) ideally the network hub (remember to add the RSS feed link for each site in the blogroll).
There’s a lot that can be done with this plugin, and I’d be interested in hearing your suggestions for improving it.
