How much computer space does Fluther occupy?

I’m just mildly fascinated by the idea that the entire flutherverse is contained in a few (?) beige machines humming away in some hovel in San Francisco, maybe with Ben’s (or Tim’s) socks drying on top. So this whole rich little world where so many of us spend so much time, and that holds the record of so much jelly wisdom—how much disc space do we occupy?
