As a flickr user, I am many things, none of them would I consider to be in the professional realm, but purely for hobby's sake. I create with paper, but I also take lots of photographs and enjoy editing them using overlays. I also have discovered flickr is a great place to share my photos that I know I'll never combine with paper and save for my family's memories. So I am adding those, with a creative common license so someone else can use them if need be. That just makes sense to me and I'm glad I found that.
