Here is part of his analysis:
The one everybody keeps saying is the natural heir to Google Reader, though, is Feedly.com. In fact, Feedly says the ranks of its four million users have swelled to seven million since Google’s Reader death sentence was announced.
It requires a free plug-in for the Firefox, Chrome and Safari browsers. Three factors in particular make it useful.
First, the biggie: Simply logging into Feedly with your Google name and password instantly re-creates your Google Reader setup. All of your news sources, favorites and tags — category names that you can apply to certain articles, for ease in rounding them up later — magically show up in Feedly, ready to use. The synchronization is two-way; until July 1, you can bounce between Reader and Feedly to your heart’s content, and your newsreader worlds will look identical.
I plan to try a switch soon.
