Seems like there has been a lot of new stops added. I conntacted them and they kinda gave me a generic reply. This is what they wrote.
Thanks for writing in.
While we are not accepting new PokéStop/Gym submissions directly through Pokémon GO at this time, you can submit a request for a location to be added to Pokémon GO through Ingress, another game offered by Niantic. Submissions will be reviewed by the Ingress player community for inclusion in Ingress and some of these locations will also be added to Pokémon GO. However, please keep in mind that not all Ingress Portals will become Pokéstops or Gyms.
In the meantime, if you are having trouble finding PokéStops or Gyms near you, please try visiting a local park, tourist attraction, or other interesting and historical locations in your community.
Also, I take this opportunity to clarify that Pokémon spawns are random and are different for each player, If the Pokémon is in the nearby list then you must walk around to find them. Keep exploring the nearby area and I am sure that you will see Pokémon.
Let us know if you have any further questions.
