You completely give up control of your traffic to search engines and social platforms. Along with email newsletters, RSS is among the handful of options remaining to bloggers for establishing a direct communication channel and relationship with readers. With no gatekeepers.
The readers who subscribe to your RSS feed always see all of your posts. No matter what Google, Facebook, or Twitter decide.
What if only a minority of readers subscribe to your RSS feed? Is it still worth it?
They are the readers you want. The superfans who share your work. They may be bloggers themselves and link to your posts from theirs, or enable other opportunities such as guest blogging or podcast interviews.
Those few RSS subscribers are much more engaged and valuable than the many who don’t even click links on social media.Paolo Amoroso, Why Your Blog Still Needs RSS
