I'm just saying that by the time you are done building this empire it involves like 600+ consoles.
The way I see it the average surfer coming in will see 5-6 at the most.
1 on entry (from the first FPA) and one when exiting the Exit that just popped. (2 so far)
same thing for when he goes from the sites to a new niche. (2 more)
and 2 more when exiting the hub.
