I think so, yeah. The networks were already there; if they had the foresight to see how FB would eat their lunch, they potentially could have integrated customizable user profile features w/ a "wall"-like functionality into the chat platform, and nipped FB in the bud when it was still perceived as a white-collar walled garden (a rep that persisted for a couple years even after they opened it up beyond EDU). "Facebook is for college snobs; Yahoo is for everyone!"
