I used selfoss about 5 month. As a replacement of Google Reader, it is good, but not good enough. The development is slow. The duplication of items still there.
Now I give it up and go for Feedly.
Feedly is a Cloud Feed Reader platform.
I can read feeds on desktop. I can read feeds on my Android with Feedly App.
Feedly will tell you how many readers on a particular blog feed. Look at one of my blog, it has 1K readers.
Blog feeds reading can be done at any small piece of time. Using mobile device is a very important feature.
