i have 1700 pics on Flickr 98% non pool and in 3 years i think i have received 4-5 comments. Im sure they make it just as hard. Signing in with Facebook means you have to turn 'apps' on and then they tell you-"Ok you realize we now have access to everything you post, your FRIENDS list and so on. I just wont allow that.
I don't blame you. Before Smugmug changed its format, we had 298 posted comments, many of which were very informative. But with this new format, we will probably get very few additional comments. If you or any other AZ poster wants to put a comment on a photo, you can just PM it to me and I'll put in ont the Smugmug site for you. That's the best I can do.
