Why Facebook is the only model of "social network" and its features considered the canonical "social network" features? No one is ever going to make a social network that does not resemble the experience of having infinite things to read and the urge to share everything that happens to you in a personal space, expecting it to be shown automatically to others?
Is this really how a "social network" in the real world works?
I hoped also that the fact that there was a comment attracted more people to the discussion about your library (and also my rant), because it seems a nice piece of software.
