My 2 cents:
I'd imagine that the training programs are in the same boat as the applicants. They would like to get their top group but are aware that nobody gets all of their top picks. They want to express interest so that the applicants feel the love, but they also don't want to be annoying. Most probably do contact the people who are in their top cluster but are unsure as to how far down to go in terms of calling since they would end up showing love to people who who won't match with them. They don't want to get the reputation as a tease/liar and so wouldn't want to promise anything to people outside of their top handful. The people who do the interviews are also, I imagine, busy, since they have plenty of other things to do than make contact with dozens of senior medical students every year. They are also, presumably, aware that the whole thing--including the correctness of their list--is a crapshoot.
I would probably not make a big deal about getting or not getting phone calls. Call them if you have a specific question or concern. If the training director calls, however, I would call back since, frankly, I think it's kind of rude not to do so and, worse, the lack of a callback indicates a lack of interest and will likely drop you in their rankings.
Finally, I don't care much whether the director writes me a love letter as an applicant. I care much more whether they recruit smart, hard working residents and faculty; whether the general institution respects psychiatry; whether the town is compatible to my lifestyle; etc. As for training directors who want to blow me kisses... I mean, I already have a mom and don't need another one.
So it won't last long!
