I have had some time to observe how 500px operates. After receiving an email back with an answer to my concerns, it appears the owners of this site don’t intend to listen to suggestions from their members. As long as the money keeps rolling in, they won't change. This site has such great potential. It’s too bad they don’t address the issues that are happening. Not only the dislike button but their so called “wonderful” algorithm is far less than impressive to me.
A big thanks to the people who commented and voted on my images. I have met many wonderful people from all over the world.
