Although iPhones dominate the camera type and many users use the 1TB free storage to use the service as a backup/dumping ground for their smartphone's snapshots, there is still a core of serious DSLR users using groups, tags, and so on, and they are still producing the best, most interesting photos on the site.

An Independent Analysis of Flickr’s Most Popular Tags
Comments
Flickr very kindly closed my account without notification, despite my using it regularly. So yeah, screw Flickr.
Flickr has my business now that google photos is an organized mess of an app/website to use.
+Dave Dean That's weird! Sorry to hear that.
+Jose Navarro Flickr has always been really good for organizing, tagging, albums, groups, and the strong search with "interestingness" sorting capability enables people looking to license images find them.
G+ has been great for its interaction, if anything Google should approach Yahoo to see if it can become an interaction layer for the 50 million active monthly users on Flickr, especially now that Google Photos had been split off (and oddly, seems to be losing features, not gaining).
