I understand perfectly the reasons behind it.

Maintaining a site like this is sometimes very rewarding soul-wise but tiring on the monetary side. To be honest I've gone through the idea of closing the site a few times too. On the bright side, I've had also good users that helped me a lot and that made me want to keep the site running as free and as open as possible.

I've been thinking on a way to reduce server bills greatly, as I'll be jobless as well this winter, and I think I've pretty much sorted the issue, at least for now.
