The change is a little jarring, but it still works the same, and I like the new set/gallery view.
I do like the new gallery view.
Interestingly, this morning I read a Gizmodo article on the subject of how Yahoo destroyed Flickr, or rather the promise that Flickr once had. Dunno about that article, though. It's premise was that Flickr could have beaten Facebook to be the defacto social site. I'm pretty sure I've heard that said of a couple of different sites, so the premise begins to ring hollow after the umpteenth time.
