Hmm... it's certainly an idea worth kicking around.
We had basically planned to devote our energies to baseball and football for now, but nothing's etched in stone yet. (We did, at any rate, reserve the domain name already when launching this project...)
One problem is that none of us are true hockey specialists. I'm the only one here who plays fantasy hockey at all (usually gm style), and I'm not really much of an expert. Another is minor details like server fees and the like.
Maybe the first issue could be overcome by making such a site even more forums-based than this one, and/or by more actively asking for guest articles. And who knows - maybe we could find a sponsor to cover the second problem.
The biggest problem might be time, however.
Anyway, I'm just thinking aloud right now. It's certainly worth giving this idea some more thought. Hmm...
