Whoa an EM that talks to clients? A rare treat. I just got a browbeating because I (an IC) didn't jump at the chance to do more (that) for ~free~ growth. Ahem.
Mind you, we have piles of both kinds of PMs: product, project. Best I can tell, they play video games between calls/status updates. Forgot the blur on more than one occasion. Clownshow, myself included.
