In certain parts of the world, you quite literally do not have a choice. For example: I’m in a rural community on an island. No one uses any other website to post anything, from local classified ads to events to important city/community stuff. The choice isn’t to use a better alternative but whether a person here has social contact with anyone locally at all.

No, moving is not a realistic option, especially not moving as far as we’d have to move; even the biggest city in the province doesn’t use anything else.
