Regardless, the real question is how do we strap these things to a shark's head.
It's can't just 'strap' a laser weapon to a shark's head because of the constraints Newtonian Physics and Euclidean Geometry. However, you can achieve something like that with some workarounds from Quantum Mechanics. <|:-)
To some it all: that's Great Britain; don't try it in at your hometown.
In my perception, the social network many people may have fled from was Orkut, after it become crowded with Brazilians.
Which is super stupid, because Orkut was associated with Google and had 500M users, more than G+ could ever hope to have. The logical thing would be to use ORKUT as the basis for a new platform.
I'm a Brazilian myself, so I cannot form a valid opinion about that.
