Why are recs absolutely necessary at some schools, while not expected at others?

I totally disagree. I think recs have a very appropriate place in the recruitment process. Think of it this way; I would rather hire someone that comes to me with a personal recommendation then someone I find in a standard interview process. A recommendation from an alum that personally knows a young women should hold a lot of weight. No one should recommend a PNM for membership that they don't think would make a great member. Some people interview (recruit) very well. You hire (pledge) them and they are psycho. Hopefully you can avoid those mistakes by having a recommendation.
