I thought this would be about analytics visualization dashboard with little real estate (500px). Had no idea that 500px was a company name.
I'm not sure how well they're doing business-wise. I did notice that they recently pivoted one aspect of their business. They used to facilitate users selling prints of their works; now they've dropped that service and are building a stock photo service instead.
My relative posts a photo almost everyday and is always trying to figure out how to get a higher score; different photo subjects, posting at different times of the day, etc.
