Devotion is a new, experimental E2 statistic that is worked out by multiplying your merit by your number of write-ups. It was invented by Professor Pi after his analysis of E2 data, and may be used in future to calculate level ups instead of the current system which fails to prevent noding for numbers yet also stifles many creative noders by stopping them from leveling up quickly.
For noders on the Honor Roll (those with merit higher than 6), devotion is the condition for leveling up, but otherwise the normal voting/experience system qualifications apply.
Please see Honor Roll where the system is explained by Professor Pi in much more detail.
Update 15/10/02: Devotion is no longer going to be used as the method by which noders can level up under the Honor Roll system. Although at present the devotion values which were stated on Honor Roll as being the requirements for each level do approximate the normal distribution which is now being used instead, this will change over time as the mean merit of Level 2 noders shifts upwards.
Editor Note: 10 May '12 Whilst devotion is not a vital statistic these days, it is used as a method of sorting Everything's Best Users.
