Since the redesign I've been laying back, accessing Flickr lots less than I had been, hoping that they'd realize their "New Coke" mistake and at least offer the option of users being able to view images according to the old functionality. Some other long term Flickr user friends and online acquaintances have been posting images and comments critical of the redesign, one with decades of photos is in the process of transferring them elsewhere, and several others are looking for other options.
