It does not matter why people fold just so long as they do.
It would not matter to the science, if Howard set it up so that you got a picture of Elena in her swimsuit as wallpaper as the bonus for doing X folds in a day.
Or if you then had to do twice as much, to make it go away again.
So regardless of what you think of people who just fold for the fun of the points race.
Remember that if they leave because their fun factor has been reduced it is still the science that suffers. So their complaints need to be listened too, as them leaving has the same negative effect regardless of why they go.
Also......
On the stats are fun front I have always thought that the competition would be more open/fun. If there was a limit on how many people were allowed in any one team.
So that if you wanted to be able to say I am in a top 10 team you had to earn your place by doing a lot of folding. Rather than being member 200 odd of some huge great team.
