It really worries me about if we know the implications of the algorithms that are been used. I don't think that this is what FB intended, but more thought needs to be given to affects of algorithms.
“Normal stuff happens due to Facebook” should really be the onion take here.
Suppose there’s a headline “50% of birthday parties are planned on Facebook” - does that mean Facebook is suddenly responsible for all those birthday parties? Or are they normal events that happen to be planned on Facebook these days?
