Flickr can have a serious competitive advantage if they make photo uploads easy to see and navigate: everybody likes photos, and likes seeing themselves in photos, and it’s even nicer to see photos all arranged on a page without visual cruft like status interruptions and article links. It’s also crucial to have different ways of viewing the photos: chronological is important, but so are groupings by date and contact type.
In other words, Flickr still has the ability to kick ass in this arena. They just have to build it.
