Anthere-
I do not think that putting officially the responsability in the hand of *one* person specifically is the best option. It is not empowering people. Rather, people will tend to rely on the *head* to do things.
We also need to be careful not to let too many people speak in the name of the Foundation whenever they feel like it. This is after all a community of several thousands of members, and I think some screening needs to take place before we decide that person X can be an official press contact, or person Y can be a content partnership coordinator -- because our reputation may be hurt, because people may make deals which the Foundation does not want (and later has to undo), because people may neglect their position and fail to respond to inquiries (hurting our reputation), because people may fail to sufficiently communicate about what they are doing, and so forth.
I don't think our positions are that far apart, though, especially since you yourself mention that people would have an opportunity to object. So if they object, what happens then? Will the person be unable to hold the position they are interested in beacuse of a single objection? At this point the natural solution is again to have a vote. I believe that at the very least, any assumption of an official title needs to be prominently announced, with a certain timeframe to raise objections, and a defined process for resolving them.
I also tend to believe that such an assignment shouldn't cover very short periods of time, to avoid communication problems of the type "I'm not the content coordinator, anymore, try contacting Paul." - "Sorry, I resigned last week, try contacting Amy." etc. If one only wants to assume an official title for a *single* transaction, it is better to contact whomever is currently holding that title.
I have no problem with multiple people filling a certain role, in fact I support it, but the number of people should be limited. For example we could say "one press officer for every country, or for every 40 million inhabitants of a country", so the US would end up with 6 press officers, Germany with 2, etc.
