Gawker Media's use of virtual hosting for its sites was being discussed in PartyChat, so to verify this, I ran host valleywag.com to compare it with host fleshbot.com. Imagine my surprise when I saw this output:

$ host valleywag.com
valleywag.com has address 69.60.7.199
valleywag.com mail is handled by 1 aspmx.l.google.com.
valleywag.com mail is handled by 5 alt1.aspmx.l.google.com.
valleywag.com mail is handled by 5 alt2.aspmx.l.google.com.
valleywag.com mail is handled by 10 aspmx2.googlemail.com.

If I am interpreting this correctly, Valleywag's email is being handled by Gmail/Google Apps, which is slightly ironic.
