Just a thought - right now we have more users than photos. Quite new for me ;-).
The number of users is still growing rapidly (soon it will be 100k!), but the influx of new images is far too slow. Last week most of the pictures were added by "old" users, such as Xymonau, micromoth or Newsham. They are great, but there is no new blood here!
We need new photographers and new, different shots just to give users bigger choice, better shots, new forgotten topics and places (.
I'll try to attract some people here... I hope you will do the same.
We are reaching out to as many potential contributors as we can contact. New contributors are opening galleries at a steady clip.
