This is true for me. Flickr was the first web service I paid for, and I still do. It really was a generational leap at the time. Photos were meant to be shared, and they nailed it. Tagging and tag clouds, folksonomy, embeddable badges - these were all fresh back then and they worked well. If only they would have added the ability to tag friends early on, I think it could have taken the place of some social networks.
I really do hope flickr becomes the next flickr. I keep putting my photos there, because I like to have them in one place. However, I do have to admit that sharing them on facebook creates much more interaction and fun.
