Overall I really like the new Flickr layout, especially the main photo stream. It's more of a Portfolio that one can use rather than a collection of your photos one after the other.

What I don't like is the single photo page. The photo itself is nice and big, which I like. But once you scroll past it it's pretty much a cluster fuck of information that looks very much out of place. It looks like they didn't even bother to make it blend well with the page.
