http://jjabramsprojects.blogspot.com/2007/08/bloop.html The actual government website is linked to from the Slusho site, which was a part of the viral marketing campaign.
The site you link mentioned the Bloop being linked from youcantdrinksix.com, which seems to be down. I hope it is valid though, because I remember feeling let down with all the fake sites from the YZ ARG. And I was getting pretty into the Cloverfield experience too.
Oh yeah. Totally forgot about the Slusho website. Guess I haven't kept touch with the sites in a while. After those low-quality newscasts of the oil rig, I think I stopped paying attention.
I was expecting so much more from those tv things. Also, look at the slogan for Slusho. Then look at the number of unknown noises? That's too big of a coincidence.
