1-2pm is for ???

This is nerd sniping targeted at Lesswrongians.

"What does this cryptic note mean?"

"Hmm... Not much information... But an idealized Bayesian reasoner would definitely form a preferred hypothesis, or a set of equally preferred hypotheses... Let's see what it might be--"

] What is 1-2pm?

It is the middle of the afternoon. You are likely to be eaten by a Graehl.

Blogging? My problem is that I always end up posting late in the evening, when all the reasonable people are asleep. But I still want instant feedback, so I stay up even later waiting for people to comment. Maybe I'd do better to blog earlier, when people might actually read it that day?

You shouldn't automatically assume that it's a time span. Maybe it was shorthand for: one dash to (some place with initials p m). So get running :)

2:30 is a good time to go to the dentist.
