Hey, I've uploaded a "dump" of the database (technically it isn't a dump because the structure is different and I don't have access to the real thing). It's from early 2013, but perhaps someone will find it useful. The format is SQLite3.

Also, here's an interesting graph made from the data, showing posts per day over time plus smoothing with moving average. Note the huge spike in early 2006.
