I'd say LinkedIn's cautious, careful culture is a big reason it appeals to its target professional audience.
People like us might drool over a LinkedIn API, but, right or wrong (and I'd argue wrong) I'd bet a lot of the middle-managers that are LinkedIn's bread and butter would be spooked by an API that made LinkedIn more open and uncontrolled (like Facebook).
