I'm wondering if there are enough active Ivy fans to make a go of this type of segregated site. Looking at the activity on the H/D/Cor/B/Y boards (not a whole lot, to be kind) you've got to wonder whether this works.
It seems to me that without the large contingent of 'P' followers regularly reading and commenting on posts about non 'P' teams there just isn't enough activity to draw people to those boards.
Much as folks from those schools may not have liked the amount of 'P' activity on the old board, I've got to think it was better to have someone reading/commenting on things going on than just having lots of silence...
