Another guy had mentioned that he purchased about 1500 (i believe) bird flu domains about a year ago, basically taking up every possible variant that made any sense in all extensions. I dont know if this is true and that seems like a lot of money to spend on speculation, but then again there are people in this world that have lots of money to spend, I'm not one of them.
Definitely a cool idea though, cornering the market so to speak. I don't see much commercial use for bird flu domains, but you never know.
