You're right - it's definitely less about the community and more about showing images on flickr. I don't know if you're interested, but I have found one group on flickr that has a really strong community. The threads are incredibly busy and the conversation ranges from photo topics to completely unrelated chatter and the attitude is generally a positive one. It's a different vibe than DA, but a good one all the same. All that said...DA is it's own breed of community and it's a shame that technical issues have taken away from that.
