One thing that's apparent to me from this thread is that we (the coaches) can hold diametrically opposed opinions and be certain that we are not only right, but that we speak for others. We can believe 1-a-day worlds are too slow or just right. We can believe cost is an issue or it is not. We can believe new people join to get to D1 as fast as possible, or for a multitude of other reasons.
Speaking for myself, one-a-day seems ideal. Two-a-day would not work at all. And I have very, very little interest in D1, although that might change, of course. Is the game too tough to learn? I don't know, I am still learning. I like the game so far. Are empty or full conferences more enjoyable? I have no idea yet. But I will eventually form my own opinion on that, and all the proselytizing in the world in the forums won't be an influence.
The takeaway: we speak for ourselves, only.
Off topic: do the thumbs-up and thumbs-down thingy's at the top of each post actually work? I tried to give a post a thuimbs-up, but nothing seemed to happen. Thanks.
