To keep up with multiple favorite sites without feeling overwhelmed, creating an RSS Superfeed using app automation tool Zapier can be a helpful solution. By customizing and filtering RSS feeds, users can combine several feeds into one easily digestible feed, allowing them to focus on posts that interest them most. To create an RSS Superfeed, users need to find the RSS feeds they want to follow, add them to a Zapier workflow, filter out unwanted posts, and then create a new RSS feed with their filtered content. With this customized RSS Superfeed, users can read only the posts they're interested in, receive notifications when new content is published, and even integrate it with other apps to enhance their reading experience.
