Our campany has had EAST module ads, they just stick out a little more since yhaoo is less cluttered now. And as far as the 5K ad campains a month I'm not too fond of them, it ended up being 11Cents per view for our campaign which was 'low' they said. hMmmmm we didnt see much clickthough on them though.
However! I feel warm and fuzzy that Yahoo will soon have text based advertisements served like Overture ads within the results. hMmmm
