After Google Reader
I am currently using NetVibes. It’s OK, although not as good as Google Reader. My main problem is that it wants to do far too much, with all sort of “social media searches” and widgets and cruft. The best part of Google Reader was that is was basically just an RSS reader.
Some other possibilities I haven’t tested yet
I have seen these mentioned as suitable replacements but I have not tried any of them myself. I should really do that, to see if they’re better than NetVibes.
