From Ezra's blog, a number repeated again and again throughout the blogosphere:
I'm still thinking about that amazing 600-person town hall meeting in London, Ontario on Monday night.
Paul Berton, explaining why the London Free Press didn't bother to cover the event:
"The event was discussed and considered. It was never actually rejected, but simply didn't make the cut, for reasons, as you have so astutely observed, mostly related to staffing.
"That is not unique. You should know there are dozens of other events each year attended by 300 or more people that we also do not cover, mostly for similar reasons, although space and timing are also factors."
So, how about this as a standard rule-of-thumb: take everything the Ez says and divide by two.
Note: this is Berton's response to an email complaint. Read the whole thing and you can see that the "300" figure is originally raised by the complainer.
