I am very interested in geography and populations of different cities, and when researching those fields you often come across the population density of a city. Soon after it occured to me that edit density could be relevant in Wikia. I know everyone can view the number of edits someone has made and when the joined that wiki, and when researching someone's contributions those two factors come together in your mind and form a figure of how consistent their edits are. Further investigation would lead you to their contributions, where you would find what and when they edited last.
The process explained above is exactly what you could call Edit consistency. For example, I joined Community Central on July 13th, 2011, and so far I have made around 180 edits. If I calculated how many days, or weeks, I've been here, I could divide my number of edits by that figure. The number I come up with could be displayed as my edit consitency. This is just an idea of mine for the future, to display one's edit consistency somwhere in the userspace. This is kind of a far-fetched idea, but I thought it may be interesting to share.
However, there are several problems with my idea.The number may end up being a strange decimal that is difficult to comprehend at a first glance. Additionally, I'm not sure how the coding with this would work, but I'm sure it would be hard to come up with.
