It's a bit misleading to call these events "dinners" though, because they last half a day. People start to show up for dinners around 6 pm. This seems wrong, unless the YC dinners conclude at 6 AM.
I meant half a waking day, cperciva. When someone says "I spent half a day trying to find that bug," they don't mean 12 hours.
Huh. That never occurred to me as an interpretation.
I wonder if this is a British vs. American vs. Canadian English issue, or if I'm just slower than usual today.
