Had my first sale on the 30th.
I'm with you, Laurin...I really like Mostphotos, and link to my portfolio there wherever I have a profile.
At first I was skeptical about the lack of reviewers, but now I love it! I'm so fed up with the nit-picky review process. It's getting out of control on too many of the sites, and it's becoming entirely too difficult to get images accepted. Some of the sites look for every reason NOT to accept a photo, instead of reasons to accept it.
Let the buyers decide what they want.
