I have a bunch of favorites. One that is growing on me is Nexus. I personally know the mother of Colin Cantrell (the founder of Nexus). Jim Cantrell, Colin's father started a company (Vector Space Systems) and is building a production facility to build rockets to launch micro satellites. They will provide a network that isn't controlled by a government and will allow transactions to take place. My boss and a few co-workers were cherry picked to go work there. One of these days, I will write an article on them.
