A terrific post, as always. Thanks so much for these analyses/breakdowns. I love the point about there being multiple themes. The main theme about the inventor of the Social Network being disconnected himself ironically was the least effective for me, partly because it was the least true to life. I found the theme on class (amplified by Fincher's brilliant staging of the scenes at Harvard and of the Winkelvii) most powerful. One could say it's the multiplicity of themes and the complexity of the characters that makes the Sorkin script so brilliant--it gives each viewer their own way into the story. A friend of mine posted an essay I wrote for class this fall on TSN at
http://www.litkicks.com/WritingTheAntihero where I tried to talk about the complexity of this unsympathetic character a bit. But I think your point about Sorkin's multiply themed approach really nails it for me in re: how complexity of theme and character work together to make this an uniquely powerful script.
