Hashem is actually code - instead of using the name of God (Adonai, spelled in Hebrew (right to left) Yod, Heh, Vav, Heh) in anything but a prayer, Orthodox Jews will say Hashem - "The Name". So Baruch Hashem is actually saying Praise God.
So, from this we can learn, the owner/operator of the site is Jewish, probably Conservative or Orthodox.
Interesting. NBD, but interesting.
