S.e.o.

Is really links and content all that there is to seo?
I've been watching some y.o.u.t.u.b.e. videos and I saw Matt cutts saying that wordpress takes care of everything as far as seo is concerned.
so if I made a wordpress site with some links and get some good content I should be on my way right?
and make a blog farm or something like that. But if links and content are the only thing that's important in seo then it should be not so difficult. with that and the right keywords.
