Nslookup asks directly your name servers (those in the resolv.conf). Programs should ask the local resolver [1] , which can (and usually is) configured to look first in /etc/hosts (that's this line hosts: files dns in your /etc/nsswitch.conf). Some applications (browser, I'm looking at you!) which deem themselves more important than all the other snowflakes are starting to bypass this.
