I've been using this ever since Google Reader went to the cemetery.

Thinking about it now, I think it's absolute best feature is that it is stable. There's not this constant flow of bullshit "new feature! redesign! experience the new and enhanced look and totally fucked up interface of our new version!" that you get from most other bullshit companies. I love that. It's a great tool, because it's reliable.

Only enhancement I can think of would be some ad-filtering, as a few of my feeds have metastasized "Sponsored" content that must be filtered out before polluting my brain.
