I have read lots of doom and gloom about the recent major changes to Flickr. However I have to say that I am personally a fan of the new tile view.
In fact I was inspired enough to clean up the mess that my collections and sets had become.
The new tile view encourages scrolling through large quantities of images. Therefore I deleted almost 100 sets and replaced them with 17 public ones and a number of others just for family shots.
I never ever used the old set/page views, instead viewing my images via the excellent FlickStackr app. But now I do any serious browsing via the native Flickr interface.
About the only other thing I had to change was my profile image which was terribly low resolution. I went back to the original file, re-cropped it and uploaded it again as seen above.
I haven't shot my vintage Canon IV-S rangefiner in a long time, but it has a classic profile that serves to show off my bubble level!
