Well, I'm afraid that I can't answer your questions with an exact answer, but I can offer you some round-about information that might be useful. The family practice residency director at my school told us that they look very favorably upon extracurricular activities that show a dedication towards primary care and community outreach programs (like participating in health fairs, free health clinics). I imagine that the same would hold true for primary care clinics. Also, I heard that a UCSF primary care IM program wasn't even filled last year, so I definitely think that PC IM programs are much easier to match into then categorical programs when you are talking about the big names. However, remember that if your goal is to be a good primary care internists, your future career may actually be better served by going to a non-university affiliated strong community program that will give you more autonomy in managing complicated medical cases by yourself (less specialists support/control), and let you do more procedures by yourself (like all of the flex sigs won't be taken by GI, all of the stress tests won't be by cards, etc). Academic reputation has far less weight when you are talking about residency for primary care in internal medicine if you are just planning on going out into private practice after residency. If you are not certain that you want to go into primary care, I'd highly recc that you stick with the categorical programs.
