The popular subreddits are a write-off but there’s still good discussion if you dig a little. I like to think the mainstream subs are acting as the fall-guy for lesser known subs, leaching the awful populace away.
IRL that's somehow like Tenerife, Canary Islands, works as a popular European tourist destination: They built (in the 60s and 70s) two major centers in the dry south, not far from the airport: Los Christianos and Los Americanos. When exiting the airport, the crowds divide: all those (mostly anglophone I think) tourists who are there with their buddies for the booze and the all-you-can-eat turn left and are shuttled to those two centers, everybody else—the retired couples, the quiet types, people into hiking and stuff—heads down the highway to the right and distributes over the much larger rest of the island, including the green and more hospitable north. For all the crowds and the frenzy at the airport, Tenerife has many quiet and even lonely and downright deserted spots.
