I've been a Flickr member since 2005, and Flickr was very good to me. It's how I met my husband!
However, I find the new format to be less user-friendly, and I don't use the website much anymore. On the rare occasion that I still get messages, it tends to be from people who want to use my photos for commercial purposes without paying me.
I've now made most of my pictures private or friends-only.
