I like it as a reminder that they're there to represent their constituents, and it means lesser known places are regularly mentioned in parliament (what with it being in London)
The indirect debate strategy has always baffled me (people addressing the speaker instead of the person across the aisle), but it's a really interesting way to frame a debate and to - theoretically - avoid ad hominems. Of course in UK politics they can still say stuff like "Mr. Speaker, I believe the right honourable lord of whatsit is being rather silly".
