Bibs Feed Cat Widget

Places a Widget with categories and feeds for each category in your sidebar

Christopher Finke

Feed Statistics is a plugin that tracks statistics for your RSS/Atom feeds, including the number of subscribers, which feed readers they’re using, which posts they’re viewing and which links they’re clicking on.
To display your subscriber count, use the Feed Statistics widget.
The plugin also adds a “Feed Statistics” menu to your dashboard. This section has four subsections: Feed Statistics (Options), Feed Readers, Post Views, and Clickthroughs.
It will take a few days for the subscriber count to become accurate, so you may want to wait a day or two between installing/activating the plugin and publicly displaying your subscriber count.

Feed Statistics

Compiles statistics about who is reading your blog via a feed reader and what posts they're reading.
