There's a thread somewhat relating to this elsewhere. It does seem that a few longtimers did not come back after the format change. I took time, myself, wondering if I had not already downloaded enoucg photos of Nancy Quill, Laura Sangiacomo, etc.; the change perhaps gave some of us a moment or two to reflect on the amount of time we spend here.
I am in touch with Pedonbio. He (or she) is well, and knows that they are missed.
I've tried to do more posting of images myself, to fill in part of the gap, but I have dial-up and it's a little difficult. (It's hard to go back and see what's already been posted.) Still, it's time to pay back in.
