Heath:
Many people are too new to this site to have participated in any of those old discussions, which were often Rogue and myself going back and forth.
Yeah, would agree with you on that, though I think that's sort of the answer to your question: Back then most of the discussion was between you and Rogue, but now Rogue is gone, and you're not able to spend as much time here. Change the players, and you'll change the play. :) The discussion is different because the discussors are different.
Heath:
You have to admit that the tone of the place has changed over the last 2-3 years.
Indeed. Though, I'd say that's probably to be expected in a media like this one.
