well that suggests you have a preconceived idea of who you're going to nominate - I'm not going to go into this thinking "right well I'll nominate A and B this week but I really like C too so instead of paying attention to next week's posts, I'll automatically choose C."

and whilst I appreciate some people do that anyway, I don't. It was a system that worked perfectly well as it was, it doesn't require any extra effort counting up 3 (because it's essentially copying and pasting).
