As someone who was "on the inside" on the private BEREA forums for a while, and was a relatively active discussion participant, I'll just say that you're not really missing anything.
If you've been a member of any Christadelphian group, complete with gossip, infighting, irrational arguments, and people being shut/shot down by "authority figures", well it's a bit like that. It's just a group of people pretending to be all intellectual and playing the "I know something you don't know" game far too well. Ironically there are probably a lot of parallels between BEREA and the gnostics (2nd/3rd century), in terms of the culture.
