Well, actually there still are 54h left. Thejeff asked for an extension over the weekend, and people might just be taking advantage of the extra time. (My turn is done, except that I'm hoping to hear back from someone about something, so I haven't submitted yet. )
As for waning intrest, you'd best ask that to the people longer in the game than me. For me it's still shiny and new. Makes me feel like a vi-i-i-irgin...
