David Weinberger makes an interesting point about the nature of the change that is impacting public relations:

Now I think PR is entering a phase where it sees itself as helping companies with their public relationships. (“Public Relationships — Adding hips to public relations”?) I first heard this term at EdelmanPR (disclosure: to whom I’m a consultant), but I don’t know who coined it. I find the phrase useful because it asserts a connection to traditional PR while pointing to a new dominant possibility. It implies, in line with Tim’s thinking, that PR needs to get out of the intermediation business. It means that more voices have to be allowed to speak from within the corporation, since relationships based on a committee-produced controlled voice will fail. It explains why blogs are such a useful tool: They are public relationships. It assumes there’s persistence to the relationship, not merely press releases thrown in our faces whenever the company has some new crap to flog. It assumes mutuality. It relies on the relationships being based on frankness and transparency.
