Actually, if you really want a GOOD idea on how to run a contest, make it have to have a POINT. Something like Steve Lightspeed's contest here.

It wasn't about who posted the 500th reply. There was actually some guessing involved, so it was fun. I didn't participate to pad my postcount OR to win the money. More because it started to piss me off that I couldn't get it right.
This was the most I've ever posted in a contest thread, and yes I did try to win. But, Steve also was given directions on where to send the money and it wasn't to me.
