I know the reputation leagues are mostly fun, but:
Why did you drop the 'current user at top of page' feature (that was an excellent addition)?
- Why are the 'this week' dates not aligned with the 'this week' dates in the http://stackoverflow.com/users/recent/NNNN page?
At the moment (2010-12-31), 'recent' uses a start date of 2010-12-26, but the leagues use a start date of 2010-12-27.
The first question (now struck out) seems to have been a temporary glitch somewhere. It works as before an hour or so after asking it.
