I just noticed that flickr added a minor tweak just now. You can change the layout of your photos page. There are some small design changes as well but the Flickr logo still bears the gamma tag. To change your flickr photo page's layout, head over to flickr.com/account/prefs/layout/ and select one of 6 layouts. Just another example that small changes can do a lot. You can replace the sidebar of sets with collections - does anyone know what the difference between a set and a collection is?

Which layout will you be using?
