As a viewer, not an artist, I considered Flickr the biggest usability failure among the part of web that is actually used by people. I mean it. It was my worst photo-browsing experience ever (even lists of images on Wikimedia Commons are nicer).

I never understood why people posted photos to this website or how it became popular. Could you, or anyone, share some thoughts of that? I am genuinely interested in how people who were more target-audience felt about Flickr.
