Just an update to
this.
The average data transferred per day is still at about 2.2 GB.
There's a gigantic spike at 1:00 am (what time zone, I don't know, though) on Dec. 29. I think it's from getting heavily linked to from StumbleUpon. Either way, there were easily 5 times as many hits on that day, and almost all of them concentrated into a single hour period.
