Flickr has been able to keep naughty pics and groups and made mini social network groups that don't require real names. It's a little known bastion of the old net in some ways.
Now that oauth is pushing these logging / sharing terms updates, I am glad they are getting rid of flickr. I just hope they don't start censoring more and become ruined by investors who push mainstream ad revenue acceptance over having less censored sharing.
I understand they have ways to download your pics in batches to move elsewhere, however for me it's the groups of people who share similar things, comments using aliases, community from around the world, others sharing pics from events I'll likely never be able to visit, and easily creative commons narrow searches by type of license.
There is no way to download all of that... wonder how as much as possible could be ported from and to scuttlebutts groups, buddypress systems and the like.
It was sad watching tumblr and so many others get ruined by greedy overlords, I hope this great portal does not end the same way, and smugmug will let me continue as is.
