As is their custom, Google is killing off their Google Reader RSS feed aggregator on July 1 due to their inability to monetize the service. Here are a handful of alternatives.
Feedly – I switched over to Feedly once I read about Google Reader’s imminent demise. So far it has proven to be a worthy successor, with a nice visual presentation. As long as you switch over before July 1, it should import your Google Reader feeds automatically. Feedly also offers an excellent mobile app.
The Old Reader – Another good alternative. This does not automatically import your feeds, so you will need to export them from Google Reader first (In Google Reader, go to Settings -> Import/Export).
There are plenty of other options as well. What Google Reader replacements have I missed?
