This is really too bad. I always went to milw0rm first -- even before SANS, etc. simply because I preferred to see the exploits in code. It is one thing to hear how an exploit works, but by actually seeing the zero-days I think it makes you a better pen tester and allows you to absorb some of the style and analytic thought that went into discovering the vulnerability.

I assume someone will take up the slack though. milw0rm was great, but there really wasn't anything that special. If nothing else, we still have metasploit.
