My brother from a different mother.
The threaded view is too chaotic for my tastes. A good old flat forum style with the sensible use of quotes like this one, is my fav.
Yes. Threaded forums also suffer from all topics eventually sliding from prominence meaning old threads get retrod again and again. A good usenet thread could last for years.
I actually have some thoughts on a usenet 2.0 with cryptography and better decentralization. I should really start putting pen to paper on it.
