Admin takes alot of your posting energy. Much of it goes into answering PM's or e-mails. Then there are all the posts you find that you really can't make anymore as an admin. It's especially difficult for people who used to tend to start alot of topics I've found. Then there is the whole aspect of it being a job, not just an adventure anymore. Absolute power may not corrupt, but it sure takes the fun out of obliterating someone in a recreational flame war most of the time.
Hard to believe I had the #1 spot above Jophiel for a while heh.
