Today I join the new photo sharing website- 500px. A competitor to flickr? the charges for pro account is USD50 per year compare to flickr which only half of it by charging USD24.95. It seems that this site which was originated from Canada exist years before flickr itself. It combine social network, photo sharing , portfolio, blog and even as selling site. Beside, it even have “dislike” button!!!
Shall explore more before making any decision to give up on flickr and upgrade my 500px account.
