You mean show the threads that got the most views in the past week?

That would a much more extensive hack. The database only keeps track of the number of views, not when they occured. This is just a simple query which runs off existing data. This was the quickest and easiest comprimise I could come up with.

However, you could do different queries based on when the thread was first created. You could exclude all threads which were created more than a week ago, for instance. That would be an easy query.
