RSS

Subscription

  • * Subscribe2
    Subscribe2 provides a comprehensive subscription management and email notification system for WordPress blogs that sends email notifications to a list of subscribers when you publish new content to your blog.
  • Add to Any Subscribe (only opens a website with many services, the usage is unclear)
  • Add to Any Share/Save/Bookmark Button (similar to ‘Add to Any Subscribe’ but without widget, places icons on bottom of each page)

Feeds

  • Ozh’ Better Feed
    Your feed, on steroids : add a custom footer to RSS items with, for example, a copyright notice, a “Read More (400 words)” links, an “Add to del.icio.us” link, a list of related entries, or anything really (even custom PHP functions).
    (Documentation: Plugin Website)
  • Feed Statistics
    Feed Statistics is a plugin for WordPress blogs 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.

Aggregator

  • FeedWordPress
    FeedWordPress is an Atom/RSS aggregator for WordPress. It syndicates content from feeds that you choose into your WordPress weblog; if you syndicate several feeds then you can use WordPress’s posts database and templating engine as the back-end of an aggregation (“planet”) website.
