Quality, not quantity.
Cordex, you know how many members had 0 posts? I trimmed away about 7000 on BladeForums.com not that long ago - that's a lot of empty, taking-up-space profiles...
TheHighRoad has a lot of great advantages - a ready built mature membership; experienced moderators; an inherited community, lessons learned, etc.
Now let's all cross our fingers and pray that the site does embody it's name. I'm confident it will.
