Is it possible that the format is just getting to be more like every other format ie. the people who are good players and deckbuilders don't bother with forums apart from inside their own team, and just playtest with other people they know are good? I don't frequent the Type 1 forums here much anymore, so I can't answer this question, but: How many people who have made Top 8 at various recent tournaments are actually active posters here? Does that number tell you anything?
Apart from Steve, of course. You seem to have a great desire to _write_, not just play and succeed, so that the world at large understands your thought-processes. It reminds me a lot of Zvi.
