No need to code for meta keywords? Is this true? (googlewebmastercentral.blogspot.com)

I've heard Matt Cutts say this several times, once in person. He doesn't seem like the kind of person that would lie or stretch the truth.

Don't forget, this is with regards to google. I'm not sure what the position of the other bug guys are (but if bing is just copying google, I guess they're the same).
