I can't understand whu Allakhazam makes tradeskill recipes a Premium service, when it's free at eqtraders.com. It's not like everyone doesn't know about eqtraders. For Everquest (at least), it's probably the 3rd most popular site (eq players, alla, 1, and 2).
It doesn't take a web analyst to see the pattern of high bounce rates on pages with recipes. Keeping bounce rate low is key for ad display revenue.
