Advertisers Wary of “Open” Websites

Scott Karp looks at why more ad dollars haven’t been shifted to social networks and web sites that allow anonymous commenting:

“Sites built on open systems, which turn content creation and publishing into a free for all, will find it increasingly difficult to get their share of brand advertising dollars. Sites that that can harness the dynamism of the web, and can do so in a defined context that provides advertisers with the right degree of predictability and comfort (think Google search results), will likely be the big winners.”
