For each service when something new comes up in my lifestream (everything i've done) you should make it so each service is grouped together like it is on friendfeed. For example for Digg it could say you have dugg 12 stories and there is an expand button so you can see them all separately. This would be really helpful for people who have a lot of services or post a lot.
It would be cool if the flickr photos would expand on the page when you click them instead of going to the page. Kinda like it does on the tumblr feed page.
