Popular This Week is a plugin similar to Popularity Contest, but only records hits that happened in the last week. It then shows the most popular posts or pages in the last week as widget you can use in your theme.
It’s useful for high volume, high traffic sites where posts age quite quickly, and you do not necessarily want to direct your users to old content, but what people are reading right now. An example of the widget being used is here: http://www.nouse.co.uk/

Most Popular Tags is a WordPress plugin that allows you to display your blog’s most popular tags or categories as a sidebar widget. The plugin takes advantage of the new Widget API introduced in WordPress 2.8, allowing multiple instances of the same widget, each with it’s own unique configuration. You can specify how many tags/categories/link categories to show, the size of the smallest and largest ones, which unit and format to use as well as advanced ordering options.
