>As someone who was a big fan of Reader and worked at Google at the time (not on G+): I never understood why they didn’t try to put Reader into G+.

Oh there were many post on HN about the politics of G+ at the time, how meta ( Facebook ) are going to crush them with social graph etc. And G+ was effectively its own little organisation within Google. I remember there were something about RSS they didn't want. But I guess I have to dig up my bookmarks to find it.
