Who sucks more in this billboard standoff?

Someone who commented on my pregnant-Bears-fan post (boy, must that woman be pissed off) linked me to his weblog, home to a discussion about Clear Channel yanking a billboard promoting Mark Stevens’ yourmarketingsucks.com. The basic story is that a random Net Jets executive, concerned for his daughter’s well-being, called shenanigans on one of Mark’s billboards. More to the point, he warned Mark that “the full wrath of the Berkshire Hathaway empire” would drop on him like an Acme-brand piano if he didn’t take it down.
