Reeder (RSS App from App Store) uses 60 GB of disk space. How do I clean this up? &gt; pwd
/Users/seline/Library/Containers/com.reederapp.rkit2.mac/Data/Library/Application Support/Reeder/rkit
&gt; du -sh * | gsort -h
8.0K    rkit-edit.db

I subscribe to about 200 feeds, lots of Imgur feeds with pictures and videos.

Is this behavior normal? How do I clean this up?
Reeder's cache can get cleared in its preferences:



Unlike the iOS version you can't limit the number of articles in the cache though.
