RSS-filter: Mute filter for RSS
All credit for this goes to Sam Mellor, who wrote this. Gabe, from MacDrifter, has a great post how to set it up though.
The script runs and basically searches for keywords in your subscriptions on a feed-by-feed basis and marks those read that include a specific keyword (like SXSW).
Great stuff. Check out RSS-filter.py’s GitHub repo.
