Flickr has many many good photos and I created this group to keep those favourite photos I tagged into one collection. Most of them are selected from my contacts.
I understand it is difficult to define the group rules. I just think that good photos should have a number of views and favourites recognized from other Flickr friends (e.g. some personal photos in general will not be tagged by some others). Also max 10 photos per month per member (no personal or nude photos).
