Theres only a couple of subs that have activity resembling a reddit community. DebateAltRight, TumblerInAction, and RealIncels are the biggest groups, as these were all booted from reddit and came here, and probably the only ones that have enough activity to act as standalone subs.

Most of the users here are using all of Saidit like it is one big sub. There are only around 100 users here, and everyone knows each other for the most part and respond all across the subs. I recommend using the 'ALL' tab, there just aren't enough users to create indiviudal communities around each subject
