I meant to say that I never used Google Reader's sharing mechanisms.

Those features of Google Reader (friends, sharing) were useless dupes of other features present elsewhere on other websites (Facebook, Google+, Twitter). I already have enough friend lists to maintain as is.

I used Google Reader for reading, and that is it. I don't care that they integrate it with Google+, although to me it makes sense. I just care that they remove the useless separate list and ecosystem.
