In which case, I am content to withdraw my suggestion that we try regulating reputation. The only other forum I'm used to it from, from what I can tell, restricts reputation to something you give to people who answer your questions in help threads, but on reflection that doesn't need to be the only use and we're free to experiment.

As for "excessively high": hey, I contribute a lot to this community. And I'm able to bump up other people quite a bit as a result, stimulating the economy.
