Overall reputation scores are headed nowhere but up. Pretty soon there will be thousands of mods. What to do? Thoughts on possibilities:

• Thousands of mods is fine. Carry on.
• Adjust the threshold values for high-level SO privileges.
• Do a straight-up inflation adjustment. You had x rep, then at the turn of the year we applied the Consumer Rep Index to all scores, now you have (x / inflation) rep.
• Implement a rep decay mechanism, so that inactivity sheds some of the overall rep that's built up.
