Regarding the argument, I don't think Facebook is going to be a serious mechanism for good or evil until the company begins to take measured actions aimed at a long term goal other than "be big" and "make money." Things like the poor logistics for the API roll-out, constant minor changes, bug-inducing updates, etc, are signs of internal disorganization. I can't see either short or long term stability within that chaos.
I am also curious about Zuckerberg. I have heard both extremely negative things (arrogant), and very positive things. As usual reality is probably closer to the mean.
