How many Freepers do you think lurk or subscribe to r/The_Donald?
Hard to say. I see it mentioned on FR here and there, so I can at least think it gets a few hundred people here are reading it at least. It’s more fast-paced, edgy, and very youth-oriented so many on FR are likely lurkers. Very different environment.
It has 665 thousand people subscribed to it, so I can only assume that maybe 500 - 1K are regular FR posters or are visitors to both.
