Nothing boring about Borean...?

I've been running around questing in Borean for 2 days now, and there don't seem to be any people about at all. I remember when I first hit Northrend, Borean and Howling fjord was teeming with players, to the limit of not being able to find quest mobs at all. Ok, so that was when wotlk just came out and *everyone* and their dog was starting Northrend.

These days, Dalaran is packed with 80s, but where is the regrowth? OK, on a Saturday morning there are hundreds of people in Elwynn, but they never seem to get beyond Westfall.
