WordPress MU

I haven't seen any traffic on this topic since 1.5.1 was released. What is the recommended way of aggregating sub-blog posts onto the main MU blog? I really liked the method list-all-posts worked by displaying only the latest post from each page, but that code is old and surely something better is available.

Any suggestions?

There's a number of options available, all recently discussed in depth.

most-recent-posts & using the sitewide feed come to mind.
