Lots of 10,000 NuShares are $18 right now if you contact me at the Bitmessage address in my signature. They are not available to the public though. Individuals who have skills that will benefit the Nu network be offered NuShares at this price. Having been of benefit to Peercoin or some other cryptoasset in the past is also relevant. So if interested, write me and let me know what you can do for the Nu network.
For the record, I'm not really pleased about NuShares getting out in wild just yet, though I knew it would happen to some degree at this point in time. Right now shareholders need to manually configure their vote and change it as conditions warrant. That is why you have to be involved to have NuShares sold to you from undistributed shares. Soon shareholders will begin to use automated data feeds to configure their vote dynamically. The idea is there will be many entities trying to convince shareholders that their data feed has values that optimize the network. As the Nu architect, I've also begun thinking of ways to punish those who don't configure their vote at all.
In summary mechanisms to make being a shareholder easier have been planned for six months, but we haven't prioritized their implementation yet.
Finally shareholder screening times are currently under 24 hours.
