Here's another one I link to because it includes a comment by Google about this 7-pack thing (not that it says anything useful)
We're continuing to work out the best ways to show multiple results from a single site when it's clear users are interested in that site. Separately, we're also experimenting with varying the number of results per page, as we do periodically. Overall our goal is to provide the most relevant results for a given query as quickly as possible, whether it's a wide variety of sources or navigation deep into a particular source. There's always room for improvement, so we're going to keep working on getting the mix right.
