I wonder if that works for other notable people that get a lot of email?
The email volume line graph. Are those data points per hour? every half hour? How can they have a seemingly continuous line graph for this histogram-style data?
The "<20 words" graphs.. they don't look cumulative but the labels make them seem like they are. The correct labels should be, for example, "20 <= w < 30".
"I've asked the Gmail Meter folks to add a chart showing reply ratio on emails less than 30 words versus emails greater than 100 words. When I get that chart I will publish it here because I think that is single best secret to getting a reply from me."
Pretty good place to start if you want to get a response.
