Well, people really love those tumble weeds. We are still getting hit with a lot of incoming traffic to that page. It started with some facebook posts, and now its spreading to some of the other social bookmarking type sites.
The internet's attention span shouldn't last much longer and RW will be back to normal. But we are likely to experience some slow downs and other issues (particularly with editing) till it passes.
Time to start thinking about expanding load capacity maybe?
