Atlas Shrugged and Objectivism Continued

The more I read about objectivism and Ayn Rand - the latest being this London Review of Books overview of her works - the more I befuddled I become at how people are simply in love with her and her books. Out of the four basic principles of Objectivism, I happen to agree with two of them:

Politics: capitalism
Epistemology: reason

But not with:

Metaphysics: objective reality (I'm more of a relativist)
Ethics: self-interest (what??)

I reviewed Atlas Shrugged here. Sure - I love the emphasis on the mind and intellectualism...but not enough of it to make it my life philosophy.
