As Matt Dabbs has also concluded, so far, my favorite replacement for Google Reader is Feedly.
Feedly is —
* Free
* Available as an iPhone, Kindle, or Android app
* Available for Firefox, Safari, or Chrome (no IE) on your desktop
* Coordinates your smartphone with your desktop
* Automatically imports your Google Reader feeds
* Actually has a better video player than Google Reader — allowing me to view more videos on my iPhone than before
* Has a simple interface — although you’ll have to go through the misery of relearning your interface habits. It’s simple — but differently simple
* Has had over 3,000,000 downloads since Google announced the murder of Google Reader. That means it has enough support that it should be around for a long time.
* Did I say “free”?
Has anyone else found a substitute RSS reader/news aggregator that you’d recommend?
