On most sites (including on main), the Community user's reputation is stuck at 1. However, if you look at the very instant that this question was posted, the [Community user](http://meta.superuser.com/users/-1/community)'s reputation here is 3. I am curious about two things:

 - Why is the Community user's reputation something different from 1?
 - Why does it have a reputation different from that on the main site?
