The way he handled Marissa on his blog:
"All I remember of it was there came a point in the conversation when Mayer had had enough. She just got up and left. I think the people remaining in the conference room were a little embarassed."

in a piece about discussion culture.
Google for "Dave Winer" returns a lot of stories that are similar. Before accepting Daves view on this, I wish people would do some research into Dave Winer.
