So, my comment just disappeared out of the blue. Let's see if I can re-create it:
Not certain your exact point(s) here...are you suggesting public relations is a dying breed and we public relations practitioners (me, 25 years) are irrelevant? If that's one takeaway, it's not one I accept.
Social media has altered public relations more than any new "tech" revolution since I began this profession. It's spawned immense opportunity to innovate, align with marketing, and measure (the biggest negative we face).
If you're suggesting PR practitioners, as a whole, are not worth their weight in salt, I have no data to suggest differently, but I'll argue that one, too. Based on my professional growth curve in the last two years, which has been fast-paced, everyone must seize the opportunity presented by social media to innovate, learn, utilize, grow and re-invent. If they don't, then that they are surely irrelevant.
