If you’ve been on the Internet long enough, you no doubt remember how popular RSS feeds were, and how RSS readers were all the rage. Late in the game, an app called Reeder made its way to the top of the list of popular RSS readers.

Today, RSS feeds have fallen out of grace with most consumers, most likely due to the popularity of Twitter, Facebook, Instagram and other sharing apps. But RSS readers are still popular among tech enthusiasts.

The developers of Reeder have graciously dropped the price of Reeder for Mac to zero, as in FREE — up until the release of version 4.0  at some point later this year.
