You mostly don't understand what he's talking about, but you're fascinated by how much content he can produce in a short amount of time. This is a bit strange though, as the quality does not come from the walls of the text and the number of threads.
Lol. Excellent point.
I think the same.
I believe that user RainbowKun is making a positive contribution to the forum and was probably being undermerited.
But I also don't share the OP's enthusiasm for his posts. I had seen some and what I see is that, maybe they are too long for a forum and to me in general they don't tell me things that I don't already know.
Quantity of very long posts does not equal quality, although I understand that he is a decent poster and may be evolving in the forum and getting more and more merits.
