RSS Feed Styles improves the appearance of your RSS feeds and make them human-readable. View the screenshots to see the before and after. RSS Feed Styles also adds subscription buttons and social sharing buttons to your RSS Feeds. This allows users to share your posts without an RSS reader.
Your blog’s RSS feed is located at http://yoursite.com/feed/ (if you use permalinks) or http://yoursite.com/?feed=rss2 (if you don’t use permalinks).
Some users already have an RSS viewer installed on their browsers, so their RSS feeds are already human-readable. However, most users (especially on Google Chrome or Apple Safari) do not have an RSS viewer. This plugin makes your RSS feeds accessible to those users.
