Gives the following URL:
http://fogcore5n3ov3tui.onion/

I can connect to it.

Is the owner's online handle known? perhaps he can provide a signed message to confirm the URL.

EDIT: there is a PGP key here: http://fogcore5n3ov3tui.onion/static/bitcoinfog-PGP-public-key.txt
Also claims this is the official thread: https://bitcointalk.org/index.php?topic=50037.0 showing same onion URL.
