Well sometimes it gets a bit long winded and I tend to approach things from a more practical standpoint, utilizing classical fallacies to create a gap between the faithful (for example) and their argument. I also try to get them to define what they are talking about so that goalpost moving becomes far more difficult. You leave things a little bit more open, which I suppose fosters more discussion. You also appear to be more reactive, which is in opposition to me- I tend to lay out bait so that a foolish debater will fall into a logical trap.
same ends are met but very differing methods.
