It's funny, I cofounded SmugMug (which bought Flickr) and was there >13 years without getting to know photojournalists. They fascinated me and I admired them, but I just didn't get to meet them.
I've been talking a little to Carol Guzy, who has won 4 Pulitzer Prizes as a photojournalist and she seems like one of the most wonderful people you could ever meet.
On the other hand, I watched Shot In The Dark, the Netflix series on independent video journalists in LA. They were all about selling to the highest bidder.
