On the other hand, my limited interactions with Smugmug have been stellar. I really like those guys and wish them luck.
The joy of Flickr was exploring the random pictures from ordinary people. I could care less about the heavily Photoshopped "prosumer" stuff that seems to be more popular on the platform. I liked seeing natural skill at composition instead of digital post-processing.
Unfortunately, it looks like SmugMug wants Flickr to be more like SmugMug, so I don't see myself buying back into pro.
Flickr to me was mostly about sharing my photos with friends and family before facebook killed that use case. I don't use facebook much any more, but no one else in my circle uses Flickr either.
Deleting photos over the limit is a bit annoying though. I seem to remember in the past they just made them temporarily inaccessible if you let Pro lapse for a bit (while travelling or whatever).
Time to whip up something that will compare what I have uploaded on flickr (4000+ photos over 12 years) to what's on my local backups so I can download what I have to and forget about the rest.
