And 9 tables with only very few one-way relations. That's something you couldn't really call a serious database. It's too simple for that, although it has a lot of binary data.

I couldn't find their database schema, so it is at least questionable if they have a real database at all (see above). Page hit count indicates nothing of query counts, as most hits are served from http-buffer.
