using language
What I noticed was that the rabbi sprinkled his talk liberally with Hebrew words, some well-known and others that could be understood from context even if you didn't previously know the words. He never used the language in a way that would leave an uneducated listener completely in the dark, but he also did not shy away from using Hebrew. I like this, a lot, and in my experience the Orthodox do this a fair bit in general. It's something that Reform Jews could learn from.
I speculate that Reform leaders, wanting to be as open and accessible as possible, shy away from this for fear of losing people. And there may be some merit in that fear, as members of Reform congregations are less likely to have gone to a full-time Hebrew school and thus been able to absorb more of the references. On the other hand, it's not as if I had that experience or have become fluent, and I can generally follow these conversations. Given a statement like "when Moshe brought the luchot down from Mount Sinai and saw the people worshipping the golden calf...", don't most people understand that "luchot" is "tablets"? That's the sort of context I'm talking about. That, and sometimes people use a term and immediately translate -- "Nadav and Avihu made an aish zarah, an alien fire, on the altar...". This just makes the educational aspect a little more explicit.
As with everything, context and audience matter. When my rabbi and I talk he uses a lot more Hebrew than he does when giving a sermon, for instance. When friends and I are discussing some bit of torah or halacha the Hebrew terms fly, though I wouldn't do that when talking with random members of my congregation. But I wonder if we don't shy away from Hebrew a little too much. It's happened in the liturgy already (and Hebrew is now coming back into favor in the last couple decades), and that avoidance helped to move Hebrew from "normal" to "strange and foreign". But maybe we should be pulling small bits of the language back into the normal lexicon of synagogue discourse, not just in worship but in conversation, as a way of making Hebrew seem less foreign and scary to folks.
