I have a Multisite WordPress installation with 7 different blogs. I want to show an aggregate of the summaries of posts from those 7 blogs in the main blog. Do you know a good way to do this?
Aggregate Summaries of Posts of Different Blogs in Multisite Instance
A couple of plugins, depending what you wanted.
http://wordpress.org/extend/plugins/wordpress-mu-sitewide-tags/
Despite the name, it pulls in all posts to the main blog or a blog called ‘tags’.

Give a list of the latest posts network-wide, all in a handy widget.
