The WordPress platform provides a number of feed subscription mechanisms for the blog readers. It exposes RSS, RDF and Atom feed formats – for both blog posts and comments.
For most practical purposes, it is good enough if your readers are able to find your default feed URL for posts that is permalinked like http://www.YourBlogDomain.com/feed. (This default URL, in most cases, is redirected to the FeedBurner mainly to get and highlight feed statistics). However, the WordPress platform also exposes the category feeds which is only available in default domain feed format (and not in FeedBurner).
The category feeds are very handy because sometimes some of your readers want to subscribe to certain categories (e.g. blogging tips) of your blog posts while avoiding general rants & updates.
The category feeds can be accessed via standard URLs such as the one below whereby the phrase in bold indicate the category to subscribe to.
(Note: It is not easy to have a FeedBurner URL for categories, unless you use .htaccess redirects)
Category Specific Feed plugins
The following plugins can help you offer category specific feeds to your readers and do a lot more as well.
Over to you
Do you have the habit of subscribing to only specific category feeds on certain heavy volume blogs? Do you think that it makes sense to go light on your feed reading and/or to reduce spam?
