I wish there was a way to decrease font size and the use of http://www.facebook.com/images/ui/UIRoundedImage.png for the rounded corners is just superfluous.

That said, it's interesting to see everyone in the firehose. And the additional ad units aren't particularly obvious. I credit them - they're clearly trying to up engagement (a user benefit), not try to stuff advertising units on the page, which was my concern.
