No 5n .info have sold yet because they're all still available. It stands to reason that it's next to go, and big time. If the worthless 5n .biz got gobbled up (and in the process), and the worthless .org in numerics, I believe .info is going to really surge. I think when people really consider the strength of the .info extension in this game, it will spread like wildfire. I believe it will rival the .net - or better.
So let's get this straight, all of the extensions have exploded, but .info is a random dead dog? Not likely. Its' time is coming, and I believe that it will be a larger run than the others once it begins.
Case in point. Everyone thought 7n - 9n .com would be next, but it all shifted to .biz, and slowly to .info, and now all 4n .biz and .info are suddenly gone. The big run on .biz took place about 30 days ago. People clearly like the shorter numerics and using the regular extensions,over the longer numeric .coms. A basic observation.
I would start silently accumulating 5n .info, and you can thank me later.
