What gave me confidence that this could work, is that Google Buzz already does a little bit of grouping, and it seems elegant enough to me. But, yes, I didn't explore the details too much about the "show more" feature. Would you list a count of the "unread items" from friends? Or would you need a slider that says "Show updates from the last 48 hours?" Then, would you need to couple this with some algorithm that bubbled up to the top the friends that you clicked "show more" on frequently? I'm not sure about the answers to all these questions, so I'll leave up to developers to figure it out.
