If you can remember the above the rest is just execution, basics etc. Making your site better than the next... now there's an ever changing challenge! (and no two sites face the exact same challenges)
I agree, making it better than the others is what every webmaster should (and I would like to believe that they already do) target.
Currently though it is a very thin line to tread (and it keeps getting thinner and dimmer) with every update like ... Panda, Penguin, EMD, etc.
