If you (like me) had been using Google Reader, it’s being retired by Google on July 1, 2013.
I recommend you switch to Feedly, a similar free service which most former Google Reader users have adopted.
From Feedly, click the blue button to import your RSS feeds from Google Reader.
There are more RSS reader alternatives listed here.
The new Digg Reader is also free. And garnering some praise.
Easier still would be to subscribe to our posts via once-a-day email. Check the right hand navigation to that.
