A new trend I've noticed is that you write a recommendation for a PhD student, and then the school calls you with a list of question to answer. They go down the list of questions mechanically and you just answer them out loud. Presumably the nice faculty member on the other side of the phone takes notes on what you say, probably including the most significant phrases.
Never mind that you spent time and effort to craft a very careful letter of recommendation that includes all the information, but conveyed with more nuance and art. I noticed this last year or the year before. It never happened to me before.
