"I believe he is a brave and able man, (applause,)"
Looking over the whole text, the use of parantheses as oppposed to brackets is probably meant to indicate that the speaker does not pause, so the audience reaction overlaps. In such situations, commas and semi-colons make more sense. That is, as oppossed to the periods and exclamations that you see terminating the bracketed phrases.
Now back to hacking.
Off-topic, but does anyone else think that over the last few days HN started feeling a bit like Reddit?
EDIT: that said, I was probably wrong with most of what I said. There's been typographical variants of 'faces' since 1881 or so: http://en.wikipedia.org/wiki/Smiley#Typographical_smileys But note how these differ a lot from what we are 'used' to. And I still doubt they'd been used in that way anyway.
I don't know. Ask Nostradamus.
