The Harvard Divestment Non-Story

I read on the Atlantic Wire earlier today that Harvard's endowment had quietly dumped its investments in Israeli companies. Several bloggers had already picked up on the story, following a report in an Israeli newspaper. This seemed strange to me (for, among other reasons, the simple fact that there is no divestment campaign targeting Harvard at the moment) so I contacted Harvard. I was told that the university was not divesting itself of Israeli companies; quite the opposite, it was moving its Israeli investments out of a developing-market fund to another fund focused on more advanced economies. An hour later, Harvard issued a statement saying the same thing.

So the question is: Why didn't anyone simply pick up the phone and call Harvard's public relations office and find out exactly what was happening before posting, and repeating, what turned out to be pure speculation?
