Press Release Tweets Seem Logical but are Journos Plugged In?

Vocus is adding a feature to allow PR professionals to notify their followers when they've put out a new press release. It sounds like a logical thing to do and probably was pretty easy for Vocus to add, so it makes sense to offer it.

I wonder however, how many folks in PR are now embracing Twitter and perhaps, more to the point of this feature, how many journalists are expecting to hear about news releases via tweets. Certainly some journalists are already embracing Twitter but does that skew toward those covering IT?
