I am interested in an analysis of words/day or letters/day published in the LW forums over time (as comments, separately to posts). Can someone point me in the direction of accessing the full database of comments in easy manual-hackity analyseable format - a csv or something... Or can someone else with that access make a graph of characters published/day.

My intention is to approximate a value for characters/time or words/time (i.e. typing speed) to grasp an understand of how much approximate "human-equivalent" time is spent on the forums, and how it has changed over the period of the existence of the forum.
