I dunno, but either my browser is blocking these ads (Firefox) or I'm just not seeing them. I always just log-on to the forums:
Autopia.org Car Detailing Forum :: #1 in Auto Detailing Discussion!
I see Palm Beach (AG, etc.) now has a forum in the sponsor section, but besides that I don't notice any ads. I don't really see where the "little guys" are being pushed out. The only recent sponsor that left was Bob (Danase) because the rates went up. It seems that over the years sponsors have come and gone. And wasn't Autogeek a sponsor a few years ago? I remember their forum was giving away free stuff at Christmas (the 12 days of Christmas?).
Until we are limited to what products we can discuss I don't really notice that much of a change..... the same guys can post in the forums, and that is basically all I pay much attention to.
