I created mapokeon.com as I found a real lack of quality information within the Pokemon GO community for locations of gyms and pokestops, everyone seems to be focusing on potential Pokemon spawns, which have proven to be not very accurate.
MAPokemon is community driven, think of it like Wikipedia, anyone can add a point and everyone can up/down vote that point too.
Found this site useful? Buy the developer a beer and help with hosting costs:Donate
