Another thing I missed last month was the SF Signal Mind Meld: What 'Sword and Sorcery' Means to Me.
Lou Anders, Jonathan Strahan, and a number of contributors (among them Moorcock, Parker, Abercrombie, Cook, and Lynch) from the Swords & Dark Magic anthology (Canada, USA, Europe) answer the questions.
Quite interesting reading. I especially liked how Scott Lynch begins his answer:
First, I think it's important to remember that there's no right answer to this sort of question. The phrase I like to use is that all our in-genre labels are connotations without the benefit of denotations. They're trends and tendencies, not strict and formal boundaries.
With that said, 'swords and sorcery' suggests to me a style of fantasy in which the protagonists tend to have a fairly high level of self-interest or even selfish interest. They may certainly find themselves saving the world, but there's nearly always some degree of greed or personal ambition also driving the story.
